The Ninja Lanternshark, Etmopterus benchleyi Vásquez, Ebert & Long 2015

Whenever I’m asked if a movie has ever made me cry, I always answer, “Yes, just one. Jaws.”

It’s not the answer people expect. Old Yeller, maybe. Or Bambi. But Jaws?

Then I explain:

“The fish dies at the end.”

And now the author of this tearjerker, Peter Benchley (1940-2006), has been honored in the name of a new species of shark, the Ninja Lanternshark, Etmopterus benchleyi. It occurs in the eastern Pacific Ocean from Nicaragua south to Panama, with most specimens collected off Costa Rica. The depth range of collections is from 836–1443 m along the continental slope.

Benchley admitted that he carried a burden of regret for the violent backlash against sharks unintentionally instigated by his 1974 novel Jaws and subsequent 1975 movie. This inspired him to become not just an advocate for shark conservation, but also a tireless campaigner for ocean conservation at large. Co-founded by his wife, the Benchley Awards recognizes outstanding achievements in ocean conservation.

In line with Benchley’s outreach efforts, the authors of this new species asked four young shark enthusiasts, ages 8 to 14, and relatives of the first author (Vásquez)  to come up with the common name. Their suggestion, the Ninja Lanternshark, refers to the shark’s uniform black coloration and reduced number of photophores, somewhat reminiscent of the typical outfit and stealthy behavior of a Japanese ninja.

The authors also created a parody of the iconic Jaws poster, shown here.

Urobatis halleri (Cooper 1863)

The Round Stingray, Urobatis halleri, occurs in the coastal waters of the eastern Pacific, where its painful but non-fatal venomous spine is responsible for numerous injuries to bathers when they accidentally step on it. In fact, that’s how this stingray got its name.

Surgeon-naturalist James Graham Cooper (1830-1902) described the ray in 1863. He named it after the “little son” of Major Granville O. Haller (1819-1897) of the United States Army, who was “wounded in the foot, probably by one of these fish, while wading along a muddy shore of the bay. The wound was very painful for some hours, though small.”

The Hallers, father and son, both led interesting lives. The elder Haller fought Seminole Indians in Florida and Mexicans in Mexico, and achieved some level of fame as a hunter and hanger of insurrecting Indians. In 1863, Haller was in charge of the defense of south-central Pennsylvania during the early days of the Gettysburg Campaign of the American Civil War. At a wine-tasting party with a few light-headed officers, Haller made an imprudent but ambiguous remark that might have included President Lincoln’s name. He was accused of uttering “disloyal sentiments” and dismissed from the Army without a hearing. Haller fled this “unjust disgrace” by moving to Seattle, Washington, where he made a fortune in real estate, lumbering, farming, and general merchandising. Sixteen years later, a joint resolution of Congress exonerated Haller of any wrongdoing and reinstated him into the Army with the rank of colonel.

The “little son,” George Morris Haller, was born in 1851. According to one account, the 12-year-old boy fought alongside his father at Gettysburg, the bloodiest battle of the Civil War. In later life George became a prominent lawyer. He organized train and utility companies and served as assistant adjutant general of the Washington National Guard. When anti-Chinese riots broke out in Seattle in 1886, Haller helped to calm the mob and forestall a forced expulsion of the city’s Chinese immigrants.

It seems George had exceedingly bad luck in water. The boy who was stung by a stingray in 1863 drowned (along with two companions) when his canoe capsized in frigid water during a duck-hunting trip in 1889.

Bathylagichthys problematicus (Lloris & Rucabado 1985) and Salmo akairos Delling & Doadrio 2005

The names of these two fishes have something unusual in common. They both refer to how difficult it was for their authors to get their descriptions published.

Bathylagichthys problematicus. From: Lloris, D. and J. A. Rucabado. 1985. A new species of Nansenia (N. problematica) (Salmoniformes: Bathylagidae) from the southeast Atlantic. Copeia 1985 (no. 1): 141-145.

Bathylagichthys problematicus. From: Lloris, D. and J. A. Rucabado. 1985. A new species of Nansenia (N. problematica) (Salmoniformes: Bathylagidae) from the southeast Atlantic. Copeia 1985 (no. 1): 141-145.

Bathylagichthys problematicus is a deep-sea smelt (Bathylagidae) that occurs in the southeastern Atlantic (with one specimen known from southern Australia). In the original description, the authors state that the name is “derived from the difficulties that were encountered when studying the specimens.” This piqued our curiosity. What kind of difficulties?

We contacted the senior author, Domino Lloris, via email and learned that these difficulties included the following: unstable nomenclature within the family at the time and uncertainty regarding its higher-level classification; the scarcity of relevant literature; unavailable type specimens of related taxa; and a year-long editor-driven delay in getting the description to press.

The name of Salmo akairos, a trout from Lake Ifni in Morocco, has a similar story. The authors tell us that “akairos” means “inopportune,” but they didn’t explain how this adjective applies. So we contacted the authors and received an explanation from the senior author, Bo Delling, of the Swedish Museum of Natural History.

In 2002, Delling submitted his description to a different journal than the one in which it eventually appeared. At that time, the manuscript name was “Salmo ifnii,” referring to the lake where it is endemic. The description was rejected for several reasons, chief among them comments from a referee who argued against the description based on his personal opinions regarding salmonid taxonomy.

At around this time, Delling was contacted by a Swedish newspaper reporter who knew that Delling was trying to describe a new trout species from Morocco. The reporter even knew the manuscript name.

“I was rather upset regarding the treatment of my manuscript,” Delling told us. “And I got the impression that it was not opportune to describe the new species” based on prevailing notions of salmonid taxonomy.

Delling decided to ditch “ifnii” when he resubmitted his manuscript to a different journal, replacing it with “akairos,” or inopportune, which he believes reflected the circumstances at the time.

“Perhaps not the most mature thing,” Delling said, “but I was furious that the referee shared his ‘confidential’ assignment with this journalist.”

Goodbye, Thalassenchelys

We love adding names to the ETYFIsh Project. But sometimes we have to take them out.

Recently, a team of Japanese researchers have linked a giant larval eel presumed to be its own species, Thalassenchelys coheni Castle and Raju 1975, to adults of the Bigmouth Conger Eel, Congriscus megastomus (Günther 1877). According to a paper in the journal Ichthyological Research, specimens of C. megastomus collected off the Pacific coasts of Japan have mitochondrial DNA sequences (16S rDNA and COI) nearly identical to those of T. coheni. The researchers also strongly suspect that T. foliaceus, the other known species of the genus, is the larval form of C. maldivensis (Norman 1939). This sinks Thalassenchelys into the synonymy of Congriscus, forcing us to delete three names from the database.

But first, let’s give these names a proper send-off by reviewing their etymologies one last time.

Eel experts Peter H. J. Castle (1934-1999) and Solomon N. Raju described the genus and its two species in 1975. They believed the leptocephali were distinct enough from other eels to warrant their own genus (and possibly their own family). The genus name is a combination of thalassa, Greek for sea, referring to its distribution in central Indo-Pacific and northeast Pacific Oceans, and enchelys, ancient Greek for eel.

Thalassenchelys coheni was named in honor of ichthyologist Daniel M. Cohen of the California Academy of Sciences, “whose description of one of the early specimens [of this species] brought attention to this larval form.”

Thalassenchelys foliaceus is the adjectival form of folium, meaning leaf, referring to the leaf-like shape of the leptocephalus.

Several other eel species are known only from their larval, or leptocephalic, forms. Will they undergo the same taxonomic fate as Thalassenchelys should they be linked to earlier-named adult forms?

A smelly name: Hypomesus olidus (Pallas 1814)

Sometimes even the experts get it wrong.

David Starr Jordan, the “dean of American ichthyology,” is usually a reliable source for fish-name etymologies. He was trained in Latin and Greek (as all biologists were in the 1800s), and he even hired a professor of classical languages to help with the etymology sections of his four-volume masterpiece Fishes of North and Middle America (1896-1900). But Jordan and his team erred with this one.

According to Fishes of North and Middle America (vol. 1, page 525), the specific name of the Pond Smelt, Hypomesus olidus, means “oily.” This explanation has been repeated by many Fishes of … books over the years.

Unfortunately, olidus does not mean oily. It means smelly. (Oleaceus means oily.) And while the Pond Smelt does indeed have oily flesh, Pallas did not mention this fact in his description. In fact, he made a point of saying, “Totus male olet.” Translation: Smells very bad. Pallas also compared the smell to that of Salmo spirinchus (now known as the European Smelt, Osmerus eperlanus), adding that “if fresh specimens are sufficiently roasted acceptable food may be obtained.”

The European Smelt, like most members of the smelt family, smell like cucumbers. Some people like the smell. Pallas apparently did not.

Which brings us to the common name “smelt.” As fitting as it seems, “smelt” is not derived from “smell” or “smelly.” Instead, according to people who claim to know such things, it appears to be derived from the Old Dutch smalt, meaning grease or melted butter, referring to how the fish’s oily flesh gives it a “melt in your mouth” texture.

So, to summarize: While smelt in general means oily not smelly, this specific smelt’s name means smelly not oily.

(Our thanks to Ronald Fricke for helping with Pallas’ Latin.)

Parotocinclus collinsae Schmidt & Ferraris 1985

Who was the first African-American honored in the name of a fish?

We haven’t studied every fish name (yet), so maybe we’re overlooking one or more names. But based on our analysis to date, it seems that the earliest (and perhaps) only such name belongs to this hypoptopomatine catfish from the Essequibo River basin of Guyana.

Schmidt and Ferraris named Parotocinclus collinsae in honor of Margaret James Strickland Collins (1922-1996), an American entomologist who specialized in the study of termites. She was stationed at the Alfred Emerson Field Station in Kartabo, Guyana. The senior author credits her for making it possible to collect fishes in Guyana.

Affectionately known as “the termite lady” to friends and colleagues, Collins was the first African-American female entomologist. Born in West Virginia, she grew up in a well-educated family, showing a keen interest in nature when she was a child. She graduated from high school early (1937) and was just 14 years old when she enrolled in college. She received her Ph.D. in zoology from the University of Chicago.

Collins taught at Howard University from 1963 to 1969 and again from 1977 until her retirement in 1983. She was a professor and dean of the zoology department at Florida A&M University in the early 1960s and also taught and was an administrator at Federal City College in Washington from 1969 to 1976. While teaching at Florida A&M, a historically black school, she became involved in civil rights efforts. After she spoke once at a nearby white university on genetics and molecular biology, the department where she was dean received a bomb threat.

By all accounts, Collins was an adventurous field biologist who felt most at home in the field. She traveled to Belize, Dominica, Guyana, Cayman Islands, Suriname, Bahamas, and British Virgin Islands collecting and studying termites. Age did not slow her down, continuing to work in the field into her 70s. In 1996, on a field trip to the Cayman Islands, Margaret Collins suffered a heart attack and passed away. She was 74.

What happens when a zoologist names an animal after a person but spells his or her name wrong?

Does the incorrect spelling stand? Or should the spelling be changed to reflect the author’s intention and properly identify the person who’s being honored?

It depends.

According to Article 32.5.1 of the International Code of Zoological Nomenclature, “If there is in the original publication itself, without recourse to any external source of information, clear evidence of an inadvertent error, such as a lapsus calami or a copyist’s or printer’s error, it [the name] must be corrected.”

In other words, if the original description does not contain internal evidence that the name was misspelled, the incorrect spelling must be retained — even if the author admits in a subsequent publication that an error was made. (Errata pages or cards that appear at the time of publication are exempt from this rule.)

Here are two cases of how Art. 32.5.1 can apply and result in different outcomes, both using patronyms coined by Austrian ichthyologist Franz Steindachner (who demonstrated on more than one occasion that he was a bad speller when it came to his colleagues’ or benefactors’ names).

In 1875, Steindachner proposed the name Prochilodus hartii for a flannel-mouth characiform from eastern Brazil. Steindachner (or his typesetter) clearly spelled the specific epithet with one “t,” and did so every time in the description. But also within that paper is a statement from Steindachner that he named the species for Charles Frederick Hartt (1840-1878), an American geologist, paleontologist and naturalist, who helped collect the type specimen during the Thayer Expedition to Brazil (1865-1866). Hartt, with two “t”s, is the correct spelling of the man’s name. So, despite Steindachner’s consistent use of one “t” when referring to the fish, his correct use of two “t”s when referring to the man in the same paper means, per Art. 32.5.1, that changing the spelling from hartii to harttii is mandatory.

In 1907, Steindacher proposed the name Psilichthys (now Pareiorhaphis) cameroni for a neoplecostomine catfish from Theresopolis, Brazil. But Steindachner did not mention for whom the species was named, nor did he mention anyone named “Cameron” in his brief description. He also did not mention anyone named “Calmon,” which is most unfortunate since one year later Steindachner changed the spelling to calmoni and indicated that the species was named for Miguel Calmon du Pin e Almedia (1879-1935), Brazil’s Minister of Agriculture, Commerce and Industry, as a “token of [Steindachner’s] respect and gratitude” (translation).

In this case, Art. 32.5.1 preserves the original incorrect spelling because there is no internal evidence in Steindachner’s first description that the name was misspelled. (Although it should be noted that some catfish taxonomists choose to ignore Art. 32.5.1 and spell the name calmoni.)

Don’t feel too bad for Calmon. Steindachner named another fish after him in 1908 — the piranha Serrasalmo (now Pristobrycon) calmoni — and this time he got the spelling right.

Narcetes erimelas Alcock 1890

Deep-sea fishes pulled to the surface are probably not going to be very lively. This apparently was the case when physician-naturalist Alfred William Alcock (1859-1933) proposed a new genus and species for two specimens of slickheads (Alepocephalidae) collected from 740 fathoms (1353 m) in the Laccadive (or Lakshadweep) Sea between southern India and the Maldives.

Alcock named the species erimelas (eri = very, melas = black) for its deep-black coloration. The generic name means numb or numbness. It’s from the ancient Greek word narke, the root of the electric ray genus Narcine Henle 1834 and the present-day word “narcotic.”

The specimens that were brought on board, Alcock wrote, “were in a cataleptoid state, the whole muscular system being quite rigid, and cutaneous excitation eliciting no responsive movement.”

“Cutaneous excitation” — is that science-speak for poking with a stick?

Ricola Isbrücker & Nijssen 1978

No, the monotypic loricariid catfish genus Ricola is not named after the Swiss manufacturer of cough drops and breath mints. Instead, the name is an anagram of lorica, a curiass, corselet, or coat of mail, the root of Loricaria (which was named for the bony plates on the back and sides of L. cataphracta). According to Isbrücker and Nijssen, Ricola and Loricaria are “very similar” in all external characters except for barbel structure and shape and number of teeth. Hence the anagrammatic name.

Some ghoulish names for Halloween

Chimaera phantasma Jordan & Snyder 1900 — The Silver Chimaera of the Western Pacific. Its name, meaning phantom or apparition, probably refers to its striking appearance in life (silvery, with jet-black bands down the sides) and/or its overall ghoulish appearance common to all chimaeras.

Hydrolagus lemures (Whitley 1939) — The Blackfin Ghostshark of the Indo-West Pacific. “Lemures” means “ghost of the departed” and presumably refers to the vernacular “ghostshark,” so named for their large googly eyes, faintly luminescent body, tapering tails and overall ghoulish appearance.

Apristurus manis (Springer 1979) — The Ghost Catshark of the North Atlantic. The name manis, Latin for ghost or shade of the departed, refers to the shark’s grayish-white color

Lepidocephalus spectrum Roberts 1989 — Spectrum means spectral, an appropriate name for the Blind Spirit Loach of western Borneo. It refers to the “ghastly or ghostlike character” of its eyelessness and creamy or pinkish white coloration.

Bryconamericus uporas Casciotta, Azpelicueta & Almirón 2002 — This characin from the Uruguay River basin of Argentina and Brazil is named for the Guaraní word for an “animal-shaped ghost of the water who care[s for] streams, ponds, falls, and swamps,” presumably referring to its occurrence in small falls and pools with clear, rapid water.

Creagrutus phasma Myers 1927 — Like phantasma (see above), this name means apparition or specter, but it does not refer to this Río Negro characin’s appearance. Instead, Myers selected the name because he believed that the species was a “veritable ghost of” the sympatric genus Creagrudite (now considered a synonym of Creagrutus).

Tembeassu marauna Triques 1998 — This gymnotid, or knifefish, from the Rio Paraná basin of Brazil is named for the native Tupí word for ghost, maraúna. It refers to how the fish is “hidden” in its habitat.

The mystery of Synodus and Synodontis

The precise meanings of names that date to antiquities are always difficult to pin down. We often don’t know how these names originated or how they were first applied. And we often have an incomplete record of how the names have been reapplied to different species over the years. Synodus is a case in point.

Synodus is the type genus of the Lizardfish family Synodontidae. It appears to be a composite word derived directly from the Greek words syn (= together) and odous (= tooth). The name was applied to the Diamond Lizardfish by Gronow in the second volume of his Museum Ichthyologicum in 1756, in a pre-Linnaean publication. Our reading of Gronow’s Latin indicates that he did not explain how the teeth are “together.” Officially, the name dates to Linnaeus 1758, who created the binomial Esox synodus for Gronow’s Synodus.

Gronow published another description of Synodus in his Zoophylacii Gronoviani of 1763. Here he provided a sentence that could explain his choice of the name: “Dentes validissimi, praelongi, contigui, conferti in maxillis, palato, lingua & faucibus.” Our translation: “Their teeth are very strong, extraordinarily long, continuous, and crowded together in the jaws, palate, tongue and throat.” It’s the “crowded together” part that intrigues us. Does Synodus refer to teeth that are close together? Maybe. But there’s another explanation to consider.

Gronow wasn’t the first to apply “synodus” to a fish. The name appears in Pliny the Elder’s Naturalis historia (77-79 AD), one of the very first works on natural history: “Synodontitis is a stone found in the brain of the fish known as synodus” (translation). This “stone” was probably an otolith (which in ancient times were used in folk medicine and meteorological divination), but no one knows for sure what kind of fish Pliny was referring to. A footnote from Bostock & Riley’s 1857 translation suggests it was a bream from the genus Sparus, but they do not provide a source for their supposition. However, Bostock & Riley did provide a compelling explanation for the name. They say Synodus refers to “its teeth meeting evenly, like the jaw-teeth, and not shaped like those of a saw, so formed that the teeth of one jaw lock with those of the other.”

David Starr Jordan, the dean of American ichthyology and one very interested in fish-name etymologies (see last week’s Name of the Week), accepted this explanation. In 1882, Jordan said that Synodus is the “Ancient name of some fish,” derived from the Greek synodus, i.e., “teeth meeting, not shutting past each other like scissors.” We’re no experts on the dentition of Synodus, but we’ve yet to find any account of the genus that describes its teeth in this manner.

The similarity of the familial form of the name Synodus — Synodontidae — with that of the African upside-down catfish genus Synodontis has understandably led many to assume that the catfish name also means “together tooth.” But according to Cuvier’s Le Règne Animal (1816), Synodontis is the “ancient name for an undetermined fish from the Nile” (translation). (And yes, Synodontis does occur in the Nile.)

Do Synodus, Synodontis and Synodontitis (the otolith) all descend from the same word and/or the same fish? Or is their similarity an etymological coincidence? We will continue to research this name, but for now we’ve run out of places to look.

Pseudobathylagus milleri (Jordan & Gilbert 1898)

Has a scholar or enthusiast of fish-name etymologies ever had a fish named in his or her honor? The answer is … yes!

Jordan & Gilbert named this deep-sea smelt from the subarctic North Pacific and the Okhotsk and Bering seas after Walter Miller (1864-1949), Professor of Classical Philology at Stanford University, where Jordan was president. Miller was honored for his “intelligent interest” in zoological nomenclature.

The year before, in 1897, Miller published a paper in the Proceedings of the California Academy of Sciences called “Scientific Names of Latin and Greek Derivation.” In the first paragraph, Miller said that Jordan hired him to “review and verify the etymologies of the names of the fishes described” in Jordan and Evermann’s four-volume magnum opus, The Fishes of North and Middle America (1896-1900). [Note: this species was described in volume three.]

Miller, apparently, was quite the puritan when it came to proper Greek and Latin usage, lamenting how “scientific writers have arbitrarily departed from the philologically correct method of nomenclature established by Linnaeus” (while noting that Linnaeus himself was not without nomenclatural sin). Especially grating to Miller was the practice of some taxonomists to combine Greek and Latin words in the same name. Such names, he complained, “are enough to make one’s hair stand on end.”

Miller railed on Rafinesque, who coined “philological monstrosities” such as these names for two genera of common North American freshwater fishes — Semotilus (creek chubs) and Lepomis (sunfishes) — names that “demand the constant apology of those who use them” because they do not “give correctly the idea the author may have intended.”

We’re confident that Miller had no qualms with the construction of “milleri.”

Dallia delicatissima Smitt 1881

Sometimes the meaning of a fish name is hiding in plain sight. In this case, the meaning of the name was revealed on the two pages preceding the page we were focusing our attention on.

Dallia delicatissima is a mudminnow (Umbridae) that occurs in the Chukotski Peninsula of Russia and Port Clarence, Alaska. It’s part of a fascinating genus of freshwater fishes rumored to be able to survive being frozen alive. Such claims have not held up to scientific scrutiny, but the species does occur in some of the coldest habitats of any freshwater fish.

The specific name is credited to Swedish zoologist Fredrik Adam Smitt (1839-1904), but the name was published in a general-audience book, Vegas färd kring Asien och Europa (The Voyage of the Vega Around Asia and Europe) written by Finnish explorer Adolf Erik Nordenskiöld (1832-1901).

Delicatissima” means most delicious, but the description (in Swedish) contained a passage that confused rather than clarified. Nordenskiöld compared the species to its European relatives in the genus Umbra:

It is remarkable that the European species [called dog-fish] are considered uneatable, and even regarded with such loathing that the fisherman throw them away as soon as caught because they consider them poisonous, and fear that their other fish would be destroyed by contact with it. They also consider it an affront if one asks them for dog-fish. If we had known this we should not now have been able to certify that Dalia delicatissima, Smitt, truly deserves its name.

Why did the species deserve to be named “most delicious”? The passage did not say. We reread it several times, but apparently something was being lost in translation. Then, quite by accident, we glanced at the page that immediately preceded it. Here Nordenskiöld provided an account of the Chukches people of Russia catching fish from a freshwater lagoon:

The fish were transported in a dog sledge to [our ship], where part of them was placed in spirits for the zoologists and the rest fried, not without protest from our old cook, who thought that the black slimy fish looked remarkably nasty and ugly. But the Chukches were right: it was a veritable delicacy, in taste somewhat resembling eel, but finer and more fleshy.

On the page before that, Nordenskiöld described the fish as “exceedingly delicious.”

Next time we go out for seafood, we’re trying the mudminnow!

Gobius (now Periophthalmodon) schlosseri (Pallas 1770)

What makes this name special? It was the first specific epithet in ichthyological literature to honor a person using the patronymic “i.” Many, many fish names have been coined since then using the same construction, honoring colleagues, professors, spouses, collectors, explorers, philanthropists, and luminaries from nearly every walk of life. But this one was the first.*

Naturalist and explorer Peter Simon Pallas (1741-1811) proposed the name in Part 8 of his series Spicilegia Zoologica (“Zoological Gleanings”). The species in question is the Giant Mudskipper of the Indo-West Pacific, which is noted for leaving the water and skipping across tidal mud flats during low tides.

Pallas said the name honors “the celebrated man and my very close friend J. Alb. Schlosser, who received [this species] among fishes from Ambon [Indonesia] and kindly transferred them to me.” (Our thanks to Ronald Fricke for help in translating Pallas’ Latin.)

“J. Alb. Schlosser” is Johann Albert Schlosser (1733-1769), a Dutch physician, naturalist, and collector of natural history objects. His primary field of study was what is now called biomineralogy; in fact, Schlosser was the first to experimentally document evidence for the presence of iron in the salts of human urine. While traveling the world collecting minerals, he also collected fossils and animals. In doing so, he provided the first description of the Brine Shrimp, Artemia salina, in 1755. Many of Schlosser’s specimens from the Indo-West Pacific, including the Giant Mudskipper, came from two friends who worked as ship surgeons for the Dutch East India Company.

The last years of Schlosser’s relatively short life were tragic. His first wife died young in 1766, less than half a year after she gave birth to a daughter. His second wife was not yet 19 and pregnant when she died on 2 March 1769. Schlosser died a few weeks later on 20 March. He and his second wife were both victims of a scarlet fever epidemic.

Who was the first person honored in all of zoological literature? We don’t know. (Anybody up for figuring that out?) But we do know that Pallas named a tunicate — Botryllus schlosseri — after his good friend four years earlier in 1766.

*Pallas named two other fishes in the same publication using the patronymic “i”, but schlosseri came first (page 3). The other two are Gobius koelreuteri (page 8, now a junior synonym of Periophthalmus barbarus) and Gobius (now Boleophthalmus) boddarti (page 11).

Loraxichthys lexa Salcedo 2013: The complete and unabridged story behind its name

10/21/15 UPDATE: Molecular phylogenetic evidence published by Lujan 2015a and Lujan 2015b, combined with the overall similarity between Loraxichthys and some species of Chaetostoma, indicate that the former genus is a junior synonym of the latter.

When Norma J. Salcedo published the description of this rare loricariid catfish from Huánuco, Peru, in the journal Zootaxa, the etymology section explained the interesting name:

Lorax is the name of a fictitious character, created by Theodor Seuss Geisel, that plights for the environment. Ichthys is based on a Greek noun meaning fish. Loraxichthys refers to the fish that speaks for other fishes. The species lexa is in recognition of Alexandra Keane, sustainability activist, currently a Political Sciences student at the College of Charleston. The specific epithet is used as a noun in apposition.

But the published etymology did not explain the full story behind the name’s meaning and significance. For example, how does Loraxichthys “speak for other fishes”? And why was a political science student honored in the specific epithet? We posed these questions to Dr. Salcedo, who informed us that an earlier draft of her description elaborated on the name’s etymology but that a reviewer found it too “emotional” and asked that it be shortened. Here is the original draft:

Lorax is the name of a fictitious character that speaks for the trees, the birds, and the fishes and tries to stop the destruction of their habitat. Ichthys is Greek for fish. The species lexa honors Alexandra Keane, a third year student and Political Sciences major at the College of Charleston, who wants to learn more, about trees, birds, and fishes, to make this planet a better world for all. The specific epithet is used as a noun in apposition. In combination Loraxichthys lexa refers to the fish that speaks for other fishes, which might become extinct, unless there are more people, like Alexandra, that care enough about them.

During our email exchange, Dr. Salcedo shared additional details about the name which, with her permission, we share with you here.

I have a six-year-old child and we went to see The Lorax together, a movie for children. Then I learned about Dr. Seuss and the book he wrote where the Lorax speaks for the trees, and the birds, and the fish, etc. The fish in question inhabits, apparently, only two small streams that drain into the Huallaga River. This is an endemic lineage that is as unique as the plants that live on one slope of the mountains. By the time I was describing this species I learned that there was a team of biologists doing an environmental impact study, required by the Peruvian government, so a dam could be built. This dam will compromise the water flow in the Huallaga River basin. The lists of species generated in these kinds of studies often reveal new undescribed species or species we are uncertain about simply because we know so little about them. The genera related to this genus (e.g., Chaetostoma, Lipopterichthys) are such a taxonomic challenge that identifications to the level of species is very hard.

Nevertheless, Loraxichthys stands out (like the Lorax!) with its long evertible odontodes and the funny folds on its pelvic fins. Its osteology is fascinating! Its pelvic girdle is intermediate between Ancistrus and Chaetostoma. It lacks a nuchal plate. This fish speaks for other fishes in that drainage, those endemic organisms that share the unique environment that led to the evolution of such particular and peculiar morphology. I hope people will talk about it, learn about the Huallaga River and stop the construction of dams in the Andes. This might not happen unless (have you read The Lorax?) somebody who really cares, takes this matter into his/her hands. 

About the specific epithet. It breaks my heart to see students coming and going through college without any interest in learning. I feel fortunate to have had many wonderful students, but one student in particular caught my attention while she was taking biology for non-majors (I was teaching the laboratory portion; she was in my section). She was eager to learn biology, but not only that, she was eager to do things that could translate into change. That is when my brain went boom! This is it. She is the reason for “unless.” It is the engineers, politicians, and economists who make decisions in environmental policies without even trying to understand biological processes. This is why liberal arts education is so important.

Of course there was an emotional discourse in the etymology! But we are scientists, and are not allowed to express feelings on paper.

Dr. Salcedo’s comments about liberal arts majors reminds us of famed Harvard entomologist Edward O. Wilson, who insisted on teaching an introductory biology class to non-biology students. Because it’s these students — the future lawyers, politicians, developers, bankers, investors, engineers, corporate executives, and so — who will be setting the priorities and making the choices that decide the fate of our planet and its biodiversity.

Pagothenia phocae (Richardson 1844) with a note on Notothenia

Many fish species are named after the person who first collected the species, or the person who collected the specimen(s) that comprise the type series. This nothothen, or cod icefish, from the Antarctic, was named for its collector, too.

On the 14th of January, 1842,” wrote surgeon-naturalist John Richardson, “when the ships were embayed among ice, in the 65th parallel of south latitude, and about the 155th west meridian, a seal was taken with twenty-eight pounds of fish in its stomach. The fish were of two kinds, one a Sphyraena, the other a Notothenia [now Pagothenia], of which there were many mutilated individuals. Dr. [Joseph Dalton] Hooker made a careful drawing of the most perfect, and put several examples in spirits …

In this case the collector was a seal, a Leopard Seal, to be precise, Hydrurga leptonyx. Phoca is a latinization of the Greek phoke, meaning seal. “Phocae” means “of a seal.”

Richardson provided other interesting details about the hardships of preserving Antarctic fishes during their long voyage back to England:

The specimens thus obtained filled many casks, and numerous jars and bottles, and it were greatly to be wished that so much industry had met with the full measure of success that it deserved; but we have to regret that, during a voyage protracted for upwards of four years and a half, including every possible change of climate, and during which the ships were buffeted by many severe gales, and sustained innumerable shocks in forcing their way through the ice-packs of the Antarctic Seas, the specimens suffered very severe damage. Owing to the deterioration of the spirits in jars that were crowded with fish, and the long continued action of the brine, where that liquid was employed, very many specimens entirely perished, or merely fragments of skeletons could be rescued from the mass.

The meaning of the generic epithet Pagothenia refers to the fish’s habitat. Described by John T. Nichols and Francesca La Monte in 1936 for the species Pagothenia antarctica (now a junior synonym of P. phocae), the authors did not provide an etymology. But pagos is Greek for frost, and forms the root of the word pagophilia, i.e., one who thrives or prefers to live in ice. “–thenia” appears to be derived from the Greek euthenia, meaning abundance. Hence, a fish that’s abundant in ice.

It’s possible that the –thenia part of Pagothenia alludes to or was inspired by Richardson’s original genus, Notothenia. According to FishBase, Notothenia translates as “noton = filament + Greek, adverbial particle, then, that denotes distance or removal.” Unfortunately, FishBase is wrong. Actually, notos means south and refers to the fish’s abundance in the Antarctic. In fact, Richardson explicitly said that the name refers to the genus’ “high southern habitat, where it is probably represented by one or more species in almost every degree of longitude” (i.e., within the Antarctic circle).

Wherever FishBase got their etymology of Notothenia, it clearly wasn’t the publication in which the name was coined.

Astroblepus simonsii (Regan 1904)

Last week we featured an astroblepid (climbing) catfish from the Andes with an interesting name. This week we feature another astroblepid catfish from the Andes, also with an interesting name. The story behind this name involves a murder.

In his description of the catfish, British ichthyologist Charles Tate Regan said that the type specimens were collected at Huaras, Peru, at an elevation of 10,700 feet, by the “late” Mr. P. O. Simons. We didn’t know who Simons was, and Regan’s mention of the word “late” piqued our curiosity. What follows is a brief account of Simons’ life and death assembled from three different sources.

Born in Wisconsin in 1869, Perry Oveitt Simons moved to California in 1886 and later attended Stanford University, where he studied electrical engineering. During the summers he helped zoology students collect animals in the mountains of California and Arizona. He was so good at collecting animals at high elevations that the British Museum (Natural History) hired him in 1898 for a three-year expedition to the Andes of South America. Simons sent back valuable collections of animals, several of which — including three lizards, a snake, and a frog — were named in his honor.

While collecting in the Andes, Simons feared for his life. In his letters home he worried about the “irresponsible natives” who helped him in various ways. He mentioned two unsuccessful attempts on his life. One time he discovered that his meal was poisoned, for he was made sick by eating a little and his dog was killed by it. At another time he was robbed of everything he had and put in prison by the local authorities as a vagabond and on general suspicion. For several weeks he was unable to get word to anyone until he finally notified the British Consul, who had him released.

Undaunted, Simons set out on what would be his final journey in December 1901. He started out on foot from Argentina for Valparaiso, having first shipped his collecting materials ahead. On the night of December 20, 1901, while Simons was on the trail across the Paramillo de las Cuevas, near Cuevas, Mendoza, Argentina, he was murdered by his Chilean guide, one Esteven Paves, with the motive of robbery. Paves is said to have struck Simons on the back of the head with a “penca,” or loaded knot at the end of a rein, and then to have driven a spike through his forehead. Paves threw Simons’ body into the Mendoza River, where it was later recovered and buried, and made off with Simons’ outfit. The murderer was later apprehended and sentenced to imprisonment in Mendoza, finally dying in prison in January 1908.

News of Simons’ brutal death shocked and saddened his colleagues. British zoologist Oldfield Thomas eulogized Simons. “Brave to a fault,” he wrote, “cheery and enthusiastic, fond of a wild life, successful as a trapper, painstaking, systematic, and extraordinarily rapid in his work, Mr. Simons was the perfection of a collector, and we shall not easily find his like again.”

Astroblepus cyclopus (Humboldt 1805)

With a name like cyclopus, you’d expect this astroblepid (or climbing) catfish from the Andes of Ecuador to have only one eye. Or at least look like it has one eye. But no, the name has nothing to do with eyes. Instead, it has to do with Humboldt’s belief that living specimens of the catfish are regularly expelled from the volcanoes they live under or inside.

Let me explain.

German naturalist Alexander von Humboldt (1769-1859) spent five years exploring the New World, including parts of present-day Ecuador, Venezuela, Brazil, Cuba, Mexico, and a brief visit to the United States. He contributed at least 20 new fish taxa to the literature, including two new catfish genera that are still valid today, Eremophilus (Trichomycteridae) and Astroblepus (Astroblepidae). Humboldt was quite amazed by the latter.

In his description of the fish (herein translated from the French), Humboldt talked about a chain of active Andean volcanoes that frequently eject enormous quantities of mud. While none of these “volcanic inundations” took place during his visit, he learned from town archives and from “several very well informed persons, who have successfully devoted themselves to the physical sciences,” that these volcanoes also eject “an innumerable quantity of fish,” and have done so many times over the years.

In 1691, for example, one volcano “threw out thousands on the field of the city of Ibarra. The putrid fevers which commenced at that period were attributed to the miasma which exhaled from these fish, heaped on the surface of the earth and exposed to the rays of the sun.” Again, in 1698, “thousands of these animals enveloped in argillaceous mud were thrown over the crumbling borders” of a volcano that sunk back into the earth.

“Some Indians have assured me,” Humboldt wrote, “that the fish vomited by the volcanoes were sometimes still living in descending along the flank of the mountain: but this fact does not appear to me sufficiently proved …”. The Indians, however, did convince Humboldt that the ejected fishes were identical to those found in rivulets at the foot of these volcanoes. This led Humboldt to surmise that Ecuador “contains great subterranean lakes which conceal these fishes,” with small outlets that occasionally allow them access to the surface.

Humboldt’s claim that the catfish lives in subterranean waters has not panned out; indeed, the species appears to be quite common in surface waters. The even more fantastic claim that it is ejected from volcanoes — presumably, when the presumed subterranean waters heat up, condense and push through vents in the sides of the volcanoes — has not been verified either. In fact, we’ve seen only passing reference to Humboldt’s extraordinary account in modern literature.

So how did Pimelodus cyclopus (now Astroblepus cyclopus) come by its specific name? Humboldt offered no explanation, but anyone well versed in Greek mythology — as Humboldt and other scholars of his time period almost certainly were — would see the connection right away.

Cyclops, the one-eyed giants who forged Zeus’ thunderbolt, Hades’ helmet of invisibility, and Poseidon’s trident, lived inside the volcano of Mt. Aetna (or Etna) of Sicily.

Sebastes diaconus Frable, Wagman, Frierson, Anguilar & Sidlauskas 2015

It’s nice when modern-day ichthyologists coin names that complement those coined by their predecessors. Here’s a recent case:

In 1881, Jordan and Gilbert named the Blue Rockfish, Sebastichthys (now Sebastes) mystinus, which occurs in Pacific waters from southeastern Alaska south to northern Baja California. Jordan and Gilbert did not explain the etymology of “mystinus.” But in 1884, Jordan provided a clue: “The Portuguese at Monterey call it ‘Pesce Pretre,’ or Priest-fish, in allusion to its dark colors, so different from those of most of the other members of the family.” Mystinus is derived from mystes, the Latin word for initiated one, or priest.

Fast-forward to the present. Researchers from Oregon and California have taken another look at S. mystinus and conclude that it represents two species on the basis of molecular and morphological data. They have named it Sebastes diaconus, the Deacon Rockfish, from the Latinized ancient Greek word for an acolyte or assistant to a priest.

The name complements the species name of S. mystinus while highlighting the similarity between the two species.


Basil Nafpaktitis19 August 2015 [revised 26 October 2016]
Oneirodes basili Pietsch 1974

On 24 May 2015, marine biologist Basil Nafpaktitis passed away in hospice at his home in Charlottesville, VA , surrounded by his family and his wife of more than 50 years, Mary. His death was caused from complications associated with Parkinson’s disease. He was 85. News of his passing reached us just three days ago, which explains why this “etymological” tribute is so late.

Dr. Nafpaktitis was best known for his work on the taxonomy, distribution, ecology and functional morphology of lanternfishes (family Myctophidae) and for his studies of bioluminescence in deep-sea fishes. He is the author or co-author of 22 valid lanternfish taxa, dating from 1966 to 1995.

Only one of the three myctophid names proposed in his honor is still in use. In 1984, Becker and Prut’ko latinized the forename “Basil” to form Diaphus basileusi, described from the northeastern Indian Ocean. The authors honored Nafpaktitis for his important investigations of myctophid systematics, especially of the genus Diaphus. In 1972, Adolf Kotthaus described Lampanyctus basili, a lanternfish from the Seychelles. It is now considered a junior synonym of Lampanyctus macropterus (Brauer 1904). Two years later, Robert L. Wisner proposed the identical name, Lampanyctus basili, for a lanternfish from the South China Sea. Wisner was apparently unaware of Kotthaus’ description, which renders the latter name objectively invalid. Even if the name were not preoccupied, it would today be considered a junior synonym of Lampanyctus turneri (Fowler 1934).

The only valid fish species named after Nafpaktitis is the Eastern Pacific deep-sea anglerfish Oneirodes basili, described by Theodore W. Pietsch in 1974. Nafpaktitis was Pietsch’s major professor and Chairman of his dissertation committee at the University of Southern California. Pietsch thanked Nafpaktitis for his “guidance, encouragement, enthusiastic support, and friendship.”

It’s interesting to note that all four attempts to name a fish after Nafpaktitis have used his forename instead of his surname.

Names so offensive, they were pulled from publication

In 1857, Polish-German naturalist William (or Wilhelm) Blandowski (1822-1878) described (or at least named) eight new species of fishes from the Lower Murray River of Australia. The pages were typeset and printed and were about to appear in Transactions of the Philosophical Institute of Victoria. But two of Blandowski’s names offended members of the Institute and the entire fish section of his paper was physically pulled from the publication before it was released.

Blandowski named the Silver Perch, Cernua eadesii, after Richard Eades (1809-1867), a physician at Melbourne Hospital and a co-founder of the Philosophical Institute. Blandowski said the fish was “easily recognized by its low forehead, big belly and sharp spine.”

Blandowski also described the River Blackfish, Brosmius bleasdalii. He named it after the Revd. Dr. John Ignatius Bleasdale (1822-1884), who later became president of the Royal Society of Victoria. “A slippery fish,” Blandowski wrote. “Lives in the mud.”

Eades and Bleasdale took umbrage with these less-than-flattering descriptions. Institute officials accused Blandowski of deliberately lampooning or besmirching the reputations of two well-respected colleagues, pointing to the fact that Blandowski had a motive — simmering disagreements and financial tensions between he and the Institute. They asked Blandowski to change the names or revise the descriptions. Blandowski refused. So the Institute literally yanked the entire fish section from Blandowski’s paper on the “Natural History of the Lower Murray” after it was printed but before it was released. Inserted in its place was a short note:

“Pages 131 to 134 inclusive, with four Plates, are omitted from this volume of the Transactions, by an order of the Council, of date, 7th April, 1858.”

As it turns out, both offending names are junior synonyms of previously described species. Cernua eadesii is actually Bidyanus bidyanus (Terapontidae), described by Mitchell in 1838. And Brosmius bleasdalii is Gadopsis marmoratus (Percichthyidae), whose name dates to Richardson 1848. But Blandowski described seven other species for the very first time. Had he agreed to change the names (or descriptions) of eadesii and bleasdalii, the taxonomic portion of his paper would likely have been published, and Blandowski’s authority would now forever be associated with these species:

Ambassis agassizi Steindachner 1867 = Cernua wilkiensis

Nemataloso erebi Günther 1868 = Megalope caillentassart

Galaxias rostratus Klunzinger 1872 = Uteranka irvingii

Morgurnda adspersa Castelnau 1878 = Kurrina macadamia

Melatotaenia fluviatilis Castelnau 1878 = Jerrina dobreensis

Retropinna semoni Weber 1895 = Turruitja achenson

Craterocephalus fulvus Ivantsoff, Crowley & Allen 1987 = Kohna mackennae

Amazingly, it took 130 years to complete the taxonomy that was redacted from Blandowski’s paper.

Blandowski returned to Europe in 1859, where he tried to get his Australian research published, but to no avail. Quickly, however, he found success in the nascent art of photography. He opened a portrait studio, photographed the local gentry, and documented Prussian life as a 19th-century equivalent of a photojournalist. He never married and died at a psychiatric hospital in Poland.

A number of scholarly articles have reassessed Blandowski’s reputation and ichthyological contributions. They are fascinating to read. Here is one of them.

In addition, two fish genera have been named in his honor: Blandowskius Whitley 1931 (Monocanthidae) and Blandowskiella Iredale & Whitley 1932 (Ambassidae). But, continuing the theme of obscurity that plagued his career, both names have since been subsumed into synonymy.

Apparently, at least one hard copy of Blandowski’s fish descriptions have survived. If you access the Biodiversity Heritage Library’s PDF of the Transactions of the Philosophical Institute of Victoria for 1858, you’ll see that the deleted pages have been reinstated.

The original tipped-in note indicating that the pages had been removed is there as well.

Corydoras narcissus Nijssen & Isbrücker 1980   

One can almost imagine the smirk on Nijssen’s and Isbrücker’s faces when they coined the name of this catfish.

In Greek mythology, Narcissus was a hunter known for his beauty. One day, he saw his own reflection in a pool of water and fell in love with it, not realizing it was merely an image. Unable to leave the beauty of his reflection, Narcissus drowned. Narcissus is the origin of the term narcissism, a fixation with oneself and one’s physical appearance.

The selection of this epithet, the authors say, honors “those who recently collected undescribed Corydoras species and kindly suggested new names for them.”

The collecting party included pet-book publisher and tropical-fish tycoon Herbert R. Axelrod, ornamental-fish wholesaler and supplier Heiko Bleher, and ichthyologist Jacques Géry. The trio also collected Corydoras robustus, described in the same paper.

As far as we know, Nijssen and Isbrücker have never publicly revealed which of the trio for whom they secretly named the catfish. Our money is on Axelrod. Anybody who has read his books and articles or heard him speak at an aquarium show can get the sense that the man thinks very highly of himself. And then there’s the case of the Cardinal Tetra, Paracheirodon axelrodi, which could have been named Paracheirodon cardinalis if Axelrod hadn’t rushed a preliminary description into print.

But that’s a story for a future Name of the Week.

Two recent “celestial” names

As NASA’s New Horizons was sending back dazzling images of Pluto, we were perusing the descriptions of several new freshwater species from Asia — two of them with names inspired by humanity’s shared fascination with astronomy and beautiful distant objects decorating the night sky.

Homatula change — In the journal Ichthyological Exploration of Freshwaters, Marco Endruweit described this new nemacheilid loach from the upper Black River basin in Yunnan, China. It is named after Chang E (or Chang’e, Chang-o, Heng’e), the goddess of the moon. According to Chinese mythology, Chang E is incredibly beautiful. Endruweit’s choice of the name presumably reflects his opinion of this loach’s coloration in life.

Badis soraya — In the journal Zootaxa, Stefani Valdesalici and Stefan van der Voort describe four new species of the Indo-Burmese genus Badis from West Bengal, India. One of them, B. soraya, is named for the ancient Persian word for The Pleiades, an open cluster of bright blue stars and part of the constellation Taurus. The name refers to the blue blotch covering part of the cleithrum above the pectoral-fin base, and part of the postorbital stripe and blotches on the dorsal-fin sheath, which are often a bright blue.

Biologists have found nomenclatural inspiration from the heavens since the beginning of zoological nomenclature. (Linnaeus, for example, named the cat shark Scyliorhinus stellaris for the many star-like black-and-white spots on its body in 1758.) What’s nice about these two names is that the authors were inspired by other disciplines — mythology and ancient languages — as well.

A “soro” state of affairs: Neolissochilus soro (Valenciennes 1842)

At The ETYFish Project, part of your job is keeping our database up-to-date. So we are always tracking the current literature for new species descriptions, name changes, resurrected names, and names sunk into synonymy. In May, Zootaxa published a paper, “Cyprinid fishes of the genus Neolissochilus in Peninsular Malaysia,” in which the authors presented evidence that two species — Lissochilus tweediei and Tor soro — are junior synonyms of Neolissochilus soroides.

Something jumped out at us as being not quite right — the fact that a species named soroides, which means “like soro,” was the senior synonym of the species it was being compared to!

We looked a little deeper and discovered that the authors made a mistake. They assigned the authorship of N. soro to “Bishop 1973,” which would indeed give N. soroides, which was described in 1904, nomenclatural priority if the two taxa were deemed to be conspecific. But Bishop did not describe N. soro in 1973. That name, in fact, dates to Barbus soro, described by Valenciennes in 1842.

We alerted the paper’s editor, Larry Page, regarding the error and he invited us to write a correction. That correction appeared a few days ago, also in the journal Zootaxa. This is the first time that The ETYFish Project has published its own peer-reviewed paper.

(The full paper is password-protected, but you will see 100% of the main text in the open-access abstract. If you would like the complete PDF, let us know.)

Our conclusion is that since “Tor soro Bishop 1973” is not a valid name/author combination, Neolissochilus soro cannot be considered a junior synonym of N. soroides.

Soro, by the way, is local name for this species in Java, Indonesia.

Carapus sluiteri (Weber 1913)

One of the rarest fishes in the world was discovered only because a zoologist looked inside the body of another creature.

Carel Philip Sluiter (1854-1933) specialized in tunicates, sipunculids, echiurans and echinoderms. He was part of the Siboga Expedition, a Dutch zoological and hydrographic expedition to Indonesia from March 1899 to February 1900. The leader of the expedition was ichthyologist Max Carl Wilhelm Weber (1852-1937).

Among the many specimens that Sluiter examined was Polycarpa aurata, also known as the Ox Heart Ascidian, the Gold-mouth Sea Squirt or the Ink-spot Sea Squirt. Inside the tunicate was the only known specimen of a pearlfish (family Carapidae). Sluiter showed the fish to Weber, who named it in Sluiter’s honor.

Many species of pearlfish live inside invertebrates, including clams and starfishes in addition to tunicates. Some species are commensal and do not harm their invertebrate hosts. Other species are parasitic, however, as the title of this online article so graphically illustrates:

Absurd Creature of the Week: This Fish Swims Up a Sea Cucumber’s Butt and Eats Its Gonads

The provenance of the generic name Carapus is worth noting, too. It’s an unusual instance of a group of marine fishes bearing the local Brazilian name of fishes from the Amazon. Rafinesque proposed the name in 1810, reflecting the belief at the time that pearlfishes were related to the neotropical knifefish genus Gymnotus. (The two groups of fishes are indeed similar in appearance.) Carapo is the Brazilian name for knifefishes (e.g., Gymnotus carapo Linnaeus 1758, the Banded Knifefish). Carapus is a latinization of Carapo.

Our 15,000th name: Sturisoma festivum Myers 1942            

2/7/16 UPDATE: According to a new molecular phylogeny of the subfamily Loricariinae, this species has been reassigned to the genus Sturisomatichthys, where it is now known as Sturisomatichthys festivus (Myers 1942).

Last week we reached a milestone, of sorts—the 15,000th entry in our database. And, befitting the occasion, it’s a rather “festive” name.

Stanford ichthyologist George S. Myers described this armored or suckermouth catfish from the Lake Maracaibo basin of Venezuela in 1942. The specific epithet means pleasing or handsome. Myers did not explicitly state why he selected the name, but one look at the illustration and one can guess that Myers was referring to the catfish’s greatly prolonged fins. In addition, Myers notes that young specimens are “very prettily marked.”

The generic name was coined by English zoologist William John Swainson (1789-1855) in 1838. It’s a combination of the Latin words sturio, meaning sturgeon, and soma, meaning body, and likely refers to the sturgeon-like appearance of the genus’ type species, Sturisoma rostratum, particularly its produced snout.

The genus Sturisoma is not yet posted on this site. We hope to release the first of two parts covering the diverse catfish family Loricariidae by the end of July.

The 15,000 name total includes initial work on several orders we will begin to complete just as soon as we finish the catfishes. They include Gymotiformes (South American knifefishes), Esociformes (pikes and mudminnows), Osmeriformes (smelts and allies), Salmoniformes (salmon, trout and whitefishes), and the deep-sea order Stomiiformes.

Our progress has benefited enormously from dozens of scientists and fish enthusiasts — and a few befuddled but patient librarians — but there is a core of people we’ve turned to time and time again for help, translations, knowledge and advice, and they’ve never let us down. They include: Jose Birindelli, Bill Eschmeyer, Ron Fricke, Jan Jeffrey Hoover, Thomas O. Litz, Heok Hee Ng, Larry Page, Mark Henry Sabaj Perez, Artem Prokofiev, Erwin Schraml, Peter Unmack, and Laura Wilson. Thank you all.

15,000 down. Only 25,000 left to go!

Silver Carp, Hypophthalmichthys molitrix and Bighead Carp, H. nobilis

Our very good friend Jan Jeffrey Hoover is a fish ecologist with the U.S. Army Corps of Engineers’ Engineer Research and Development Center in Vicksburg, Mississippi. He recently uploaded a video about his work testing the swimming ability of Asian carps — specifically, the two species named above — using a mobile swim tank to learn whether flows from locks and dams on the Mississippi River can be used to help keep these non-native, invasive fishes out of the upper Mississippi and the Great Lakes. It’s a fascinating look at some fascinating research about a serious ecological threat.

Both Silver Carp and Bighead Carp are filter feeders, using extremely close-set gill rakers to remove plankton, algae, and detritus from the water. It’s this feeding strategy that attracted commercial Arkansas fish farmers, who first imported the carps from Asia to America in the early 1970s. Since catfish culture ponds often suffer from a cloudy build-up of nutrients and waste products, the fish farmers stocked the carps to filter the ponds and improve their catfish-yielding capacity. Although subsequent studies have not confirmed whether Bighead and Silver Carp can actually perform this task, the species were cultured in various hatcheries anyway and distributed to private fish farms and municipal sewage lagoons in Arkansas and throughout the Midwest. By 1980, the two carps began to appear in open waters as a result of escapes from hatcheries and aquaculture facilities, and intentional (illegal) stocking. The Silver Carp has been reported from 12 states and is established in Louisiana and probably also in Illinois. The Bighead Carp is known to occur within or along the borders of 18 states and is established in Illinois and Missouri. The spread of reproducing Silver and Bighead Carps to additional states is inevitable.

The impact of these species is difficult to predict because of their place in the food chain. Because of their large size—Silver Carp can reach 27 kg (60 lb), bighead carp 40 kg (88 lb)—these fish have the potential to deplete zooplankton populations and thereby wipe out the base of the food web that supports native filter feeders such as Paddlefish (Polyodon spathula), Bigmouth Buffalo (Ictiobus cyprinellus), Gizzard Shad (Dorosoma petenense), the larval young of other fishes, and freshwater mussels.

The imminent spread of Asian carp into the Great Lakes basin is a major worry. The fish breeds prolifically (Australian biologists call them “river rabbits”), and many fear they could overrun the Great Lakes and turn them into a giant “carp pond.”

Of course, their names, coined in the 19th century, reflect none of the ecological worries these two species now represent. The generic name Hypophthalmichthys, proposed by Bleeker in 1860, translates as hypo-, under, ophthalmus, eye, and ichthys, fish, and refers to their downward-looking ventrolateral eyes.

Molitrix means miller or grinder, but Valenciennes did not mention the origin of the name in his very brief description of Leuciscus molitrix in 1844. Nor did Valenciennes mention the fish’s teeth. Nevertheless, most ichthyologists believe the name refers to the Silver Carp’s pharyngeal teeth, which it uses to grind phytoplankton.

The specific epithet of H. nobilis has an interesting provenance. It doesn’t mean “noble,” as some references indicate. Instead, it means “well known.” Proposed by Richardson in 1845, the name appears to reflect the phrase “Eminent fish,” which is an English translation of its Chinese vernacular (phonetically spelled Tsing yu). Richardson learned about Tsing yu from John Reeves, who painted the species while working as a tea inspector in China from 1812 to 1831.

Ironically, H. nobilis continues to be a well-known fish to this day, but for all the wrong reasons.


Bailey, Reeve24 June 2015
Hypoptopoma baileyi Aquino & Schaefer 2010

This loricariid catfish occurs in the Upper Madeira basin of Brazil. According to the authors:

“The specific epithet baileyi is a patronym honoring Reeve M. Bailey (1911–2000), who collected the specimens of the new species in 1964 during an expedition of the AMNH [American Museum of Natural History] to the Río Itenez.”

One small problem: Reeve M. Bailey did not die in 2000. In fact, was still alive in 2010 when this catfish’s description was published.

The Emeritus Curator of Fishes at the Museum of Zoology, University of Michigan, passed away 2 July 2011 at the age of 100.

Osmerus eperlanus schonfoldi McAllister 1984

We like the subspecific epithet schonfoldi because it is so obscure. Very few reference works include it, and the identity of the person it honors was fun to figure out. This is probably the first time anyone’s ever contemplated the person behind the name since it was proposed in 1772.

Today, the name officially dates to a chapter on smelts written by Canadian ichthyologist Donald Evan McAllister (1934-2001) in the 1984 multi-authored multi-volume work Fishes of the North-eastern Atlantic and the Mediterranean. McAllister listed the smelt, which occurs in fresh, brackish and marine waters of Poland westward to the British Isles, as a valid subspecies of the European Smelt, Osmerus eperlanus (Linnaeus 1758).

McCallister credited the name to Eperlanus schonfoldii, published by an Irish Quaker physician-naturalist named John Rutty (1697-1775) in 1772. The full title of the privately published work is An essay towards a natural history of the county of Dublin, accommodated to the noble designs of the Dublin Society; affording a summary view.

“The ensuing Catalogue of Fishes,” Rutty wrote, “exhibits all those that I have been informed of that are either caught here [in Dublin], or brought to our Market, a Market abounding with great plenty and variety of Fishes, and much exceeding that of London in plenty and cheapness.”

One of these fishes Rutty called The Smelt, “Eperlanus Schonfoldii.” His complete description reads: “It is frequent in July and August, the flesh soft, tender and of a delicate flavour.”

Since Rutty did not include any distinguishing characteristics in his description, the name is a nomen nudum and not valid for nomenclatural purposes. McAllister seemed unaware of this when he resurrected the name in 1984. Since his account of the subspecies distinguished it from the nominate form Osmerus eperlanus, he became, by rule, the author of the name.

Eperlanus” appears to be a latinization of the Old French éperlan, of Teutonic origin, a vernacular name applied to small edible fishes that migrate to fresh water to spawn, now colloquially known as smelt (an interesting etymological story in itself, best saved for a future Name of the Week). But who was Schonfold? Why did Rutty honor him with the name? Rutty didn’t say, but he offered a clue. In his brief write-up on dolphins, Rutty wrote “Phocena quam Schonfeldus Delphinus Septentrionalium vocat.” Or, “Phocena is what Schonfeld calls the Northern Dolphin.”

So, assuming that “Schonfeld” and “Schonfold” are the same person, it appears that Rutty named his smelt after someone who had written some kind of treatise on marine life. At first, our Google searches for both spellings of the name came up zero. Then we found a bibliographical web site with an entry for one Stephan Schonevelde, who wrote a 1624 volume called Ichtyologia et nomenclaturae animalium marinorum, fluviatilium, lacustrium quae in florentissimis ducatibus Slesvici et Holsatiae & celeberrimo Emporio Hamburgo occurunt triviales. His name was spelled several ways, including Schonefeld, Schone Velde and Schoenfeld. We believe we can add Schonfeld and Schonfold to the list.

Not much is known about Schonevelde. He was born in Hamburg in the middle of the 16th century, studied medicine, and served as personal physician to the Duke Johann Adolf von Schleswig-Holstein. Like many physicians of the time period, he also was a naturalist, most interested in the natural history of the North and Baltic Sea and the fishes of Elbe River of Central Europe. He is regarded as one of the first ichthyologists of Germany and one of the most famous naturalists of his time. No one is sure when he died.

Our guess is that Rutter relied on Schonevelde’s work in writing his natural history of Dublin, and honored the German naturalist by naming the smelt after him.

And that is how a 20th-century Canadian ichthyologist inadvertently became the author of a smelt subspecies named by an 18th-century Irish naturalist in honor of a German naturalist who lived a century-and-a-half before.

Lethenteron reissneri (Dybowski 1869)

 As far as we know, this is the first time that The ETYFish Project has been cited in a peer-reviewed journal: Renaud, C. B.  and A. M. Naseka. 2015. Redescription of the Far Eastern brook lamprey Lethenteron reissneri (Dybowski, 1869) (Petromyzontidae). ZooKeys 506: 75-93.

L. reissneri is a nonparasitic lamprey that occurs in the Shilka (Russia and Mongolia) and Songhua (People’s Republic of China) river systems within the Amur River basin. It was described as Petromyzon reissneri by the Polish naturalist and physician Benedykt Dybowski (1833-1930).

According to Renaud and Naseka, “Dybowski (1869) did not specify [the etymology of the name], but this species was possibly named after Baltic German anatomist Ernst Reissner (1824–1878), as suggested by Scharpf and Lazara (2013).”

Hey, glad to have helped!

Aperioptus pictorius Richardson 1848

Late last year, Larry Page, Curator of Fishes at the Florida Museum of Natural History, emailed us saying that The ETYFish Project did not have an entry for the above-named loach in our database. We explained that we did not include the name because it was a presumed junior synonym of the cobitid loach Acantopsis dialuzonas van Hasselt 1823.

Now Dr. Page, along with Weerapongse Tangjitjaroen of Chiang Mai University (Thailand), have resurrected both the generic and specific names, in a recent issue of the journal Zootaxa. In so doing, Aperioptus replaces the genus Acanthopsoides, proposed by Fowler in 1934, and A. pictorius replaces species Acanthopsoides molobrion, described by Siebert in 1991.

The etymology of this loach’s name, and the reason it’s been overlooked by taxonomists for 167 years, are actually the same story.

Scottish naval surgeon and naturalist John Richardson (1787-1865) described the species in 1848. But he didn’t have much to describe.

Of this fish I can give no details. There were two specimens which I unfortunately placed in the hands of the artist before I had examined them, except very cursorily. While he was employed in sketching, he put them into a plateful of water for the purpose of expanding their fins more perfectly, and forgetting that he had not returned them into the spirits, they were thrown out and lost. The general aspect of the fish is that of a slender Galaxias, but there are no teeth on the jaws. The orifice of the mouth is a narrow vertical oval, which is restricted on the sides by membranous processes.

Richardson did not explain the selection of the name “Aperioptus pictorius,” but it no doubt reflects his having only an illustration from which to work. “Aperio” means to uncover, expose, open, or reveal. “Optus” means seen or visible. “Pictorius,” an adjective, means pictorial or belonging to painters. In other words, the existence of this species has been revealed by means of a picture.

And, by virtue of this very same picture, the identity of species has also been revealed, 167 years after it was named.

Lampris guttatus (Brünnich 1788)

The Opah, or Moonfish, has been in the headlines recently, with the recent revelation that it is the world’s first-known fully warm-blooded, or endothermic, fish. This, of course, got us curious about the fish’s names — both scientific and vernacular.

The specific epithetic guttatus dates to a 1788 publication by the Danish zoologist and mineralogist Morten Thrane Brünnich (1737-1827). “Guttatus” means spotted and clearly refers to the many white spots that cover its flanks. Brünnich originally named the species Zeus guttatus, placing it in the genus that is now restricted to the unrelated dories of the family Zeidae. The name Zeus, while officially dating to Linnaeus 1758 (the official starting point of zoological nomenclature), was not coined by Linnaeus. He simply provided the name for the John Dory (Zeus faber) provided by Pliny the Elder. What prompted Pliny to name this fish after the “Father of Gods and men” is not clear.

The Swedish chemist-biologist Anders Jahan Retzius (1742-1821) created a new genus for the Opah, Lampris, in 1799. That name is from the Greek lamprós, meaning radiant, brilliant or shining, and no doubt refers to the Opah’s brilliant coloration.

The derivation of the common name Opah is not so clearly known. In 1903, Smithsonian ichthyologist (and fish-name etymologist) Theodore Gill reported that the name’s first appearance in print (with an explanation) was in 1750, in a paper published in the venerable science journal, Philosophical Transactions of the Royal Society of London, under the title “The Description of a Fish, Shewed to the Royal Society by Mr. Bigland, on March 22, 1749-50: Drawn up by C. Mortimer, M. D. Secret. R. S.”

According to the authors, who described and illustrated what was clearly Lampris guttatus 38 years before Brünnich’s description, Opah is the native name for this species off the coast of Guinea, where their specimen was caught.

Gill was skeptical of this claim, noting that the Opah had never been recorded from the western coast of tropical Africa. But we now know that the pelagic Opah is a circumglobal fish whose range in the eastern Atlantic extends well past Guinea to the south of Angola. Therefore, there is no reason to doubt the 1750 claim that the word Opah is derived from a native Guinean name.


Felipe_Poey20 May 2015
Dactyloscopus poeyi Gill 1861

This week we celebrate the 216th birthday of the Cuban ichthyologist Felipe Poey. Born on May 26, 1799, to French and Spanish parents in Havana, Poey moved with his family to France when he was five, where he developed his lifelong appreciation for the natural world. Schooled as a lawyer, he traveled back and forth between Cuba and Spain, ultimately leaving Spain — and law — for settling in Cuba for good in 1833. There he became the country’s most eminent zoologist, at first studying butterflies and then increasing his focus on fishes.

Poey kept an active correspondence with the leading ichthyologists of the day, including Cuvier, Agassiz and Jordan. While Poey himself described over 130 new fish taxa — perhaps the most famous being the cyprinodontiform genera Gambusia and Rivulus — he freely shared his specimens with others, which is one reason 18 fishes have been named in his honor.

The first was Dactyloscopus poeyi, the Shortchin Stargazer (Dactyloscopidae), native to the Carribean and coasts of the Western Atlantic from Belize to Venezuela. Theodore Gill received the type specimen from Poey, whom he called as his “learned friend.” Gill continued: “In testimony of my appreciation of his labors to elucidate the natural history of Cuba, I have dedicated the species to him.”

Of the 17 other fish names dedicated to Poey, eight are considered valid species today:

• Lycengraulis poeyi (Kner 1863) — an anchovy from the Eastern Pacific ranging from El Salvador to northern Peru.

• Halichoeres poeyi (Steindachner 1867) — the Blackear Wrasse (Labridae) from the Western Atlantic; Poey described the similar Halichoeres pictus in 1860.

• Pempheris poeyi Bean 1885 — “dedicated to the distinguished Cuban naturalist” who provided the type of this Cuban sweeper (Pempheridae) in the same bottle as muelleri (= P. schomburgkii).

• Synodus poeyi Jordan 1887 — based on a Cuban specimen of this lizardfish (Synodontidae) that Poey had identified as intermedius in 1875.

• Evoxymetopon poeyi Günther 1887 — a scabbardfish from the Indo-West Pacific; Poey — whom Günther called an “indefatigable collector” — proposed the genus Evoxymetopon and its first known species in 1863 (but authorship is credited to Gill, who penned the descriptions).

• Rhamdia poeyi Eigenmann & Eigenmann 1888 — a heptapterid catfish from Bolivia, Brazil and Ecuador (the Eigenmanns offered no explanation for the name).

• Cruriraja poeyi Bigelow & Schroeder 1948 — a skate (Rajide) described from a specimen collected off the northern coast of Cuba.

• Centropomus poeyi Chávez 1961 — a snook (Centropomidae) from the Caribbean, named in honor of Poey’s “important contributions to ichthyology and specially for his studies on the genus Centropomus.”

Poey continued working until his death in 1891, writing his magnum opus, Ictiología Cubana, a compendium of all the fishes in Cuban waters. A new version of the complete, three-volume work was published in 2000, just after the bicentennial of his birth.

For Poey, being a naturalist was more than a profession. It was a calling:

While one part of humanity, diverted from its higher destiny, wages war against the other, the naturalist takes refuge in Nature’s breast, and asks the Supreme Being for peace and happiness for all. He does not aspire for riches nor power; he sees a brother in every man. He cultivates his own understanding, because it must be his faithful companion when grace, agility, love and health abandon his body in old age. He prefers to study natural history . . . because it enlarges his soul, initiating it into the sublime mysteries of Creation, which exalt in his unblemished, moral intelligence. 

To know Poey was to admire him. He was “simple, direct, unaffected, but possessed of a quiet dignity,” wrote David Starr Jordan in 1884. “Of all men I have known, he has best learned the art of growing old.”

Corydoras julii Steindachner 1906

The Leopard Cory, Corydoras julii, is a popular catfish in the aquarium trade. It’s clear the species was named for someone named Julius. No one knows who. We don’t know, either. But we have a pretty good guess.

Austrian ichthyologist Franz Steindachner described the species from specimens collected in Brazil. His description did not identify the “Julius” behind the name. This was not unusual for Steindachner, who often named fishes after colleagues and collectors but did not solidify the honor by mentioning who or why. However, Steindachner often left us clues, usually in the form of a mention or acknowledgment in a different publication.

Sure enough, Steindacher mentioned a “Julius Michaelis” in his redescription of the loricariid catfish Hemipsilichthys (now Pareiorhaphis) cameroni in 1907. Not much is known about Julius Michaelis, except that he provided Steindachner — and his German-British contemporary, Albert Günther — with fishes from Brazil. Julius Michaelis collected the type of P. cameroni. Maybe he collected Corydoras julii as well?

We don’t know for sure whom C. julii honors. But at least we now have solid evidence that connects the name of the fish to the name of a person who sent fishes to Steindachner from the country where the fish occurs.

Teleogramma obamaorum Stiassny & Alter 2015

A new deepwater cichlid from the lower reaches of the middle Congo River has been described. Its name honors a famous American couple. According to the authors:

“We name this new cichlid species from the freshwater heart of the African continent in honor of U.S. President Barack Obama and First Lady Michelle Obama, in recognition of their commitment toB&M science education, development, gender equality, and self-reliance for all peoples of African nations, and their dedication to environmental conservation in Africa and beyond.”

This isn’t the first fish species to be named after the 44th U.S. president. In 2012, Layman & Mayden dubbed a new species of darter (Percidae) from the Duck and Buffalo Rivers of Tennessee, with the name Etheostoma obama. The authors cite Obama’s “environmental leadership and commitment during challenging economic times in the areas of clean energy, energy efficiency, environmental protection and humanitarian efforts globally.”

In addition to E. obama, the authors described four other darter species in the same paper all bearing the name of a U. S. president or vice president:

Etheostoma clinton (upper Caddo and upper Ouachita rivers above the Fall Line in Arkansas), in honor of Bill Clinton’s “lasting environmental accomplishments in creating and expanding national monuments, preserving millions of acres of wilderness areas, his leadership and commitment during challenging economic times, and his continued commitment to global humanitarian issues and needs and peace.”

Etheostoma gore (Cumberland River drainage of Tennessee and Kentucky), named in honor of Al Gore for his “environmental vision, commitment, and accomplishments throughout decades of public service and his role in educating the public and raising awareness on the issue of global climate change.”

Etheostoma jimmycarter (Green River drainage of Kentucky and Tennessee), named in honor of the 39th president of the U.S. for his “environmental leadership and accomplishments in the areas of national energy policy and wilderness protection, and his life-long commitment to social justice and basic human rights.”

Etheostoma teddyroosevelt (Arkansas and upper White river drainages on the Ozark Plateau of Missouri, Arkansas, Kansas and Oklahoma), named in honor of the 26th U.S. president, for his “enduring legacy in environmental conservation and stewardship, including the designation of vast areas as national forests, wildlife refuges, national monuments, and national parks, and his efforts to forge the American Museum of Natural History, New York.”

One 20th-century American ichthyologist is reputed to have said this about politicians: “Give them the streets, but keep them out of our papers.” How do you feel about animals being named after political figures?

Mollisquama parini Dolganov 1984

The name isn’t especially interesting, but the fish is.

The Pocket Shark, Mollisquama parini, is known from a single specimen collected from the Nazca Ridge of the southeast Pacific Ocean. It’s dubbed “pocket” because of a large slit-like external opening located just above the pectoral fin, unique among sharks. (The function of these pockets is unknown; some suggest that they secrete some kind of glowing fluid or pheromones.)

On 22 April 2015, the journal Zootaxa reported that a second specimen had been discovered — not in the ocean, but in a freezer. It had been collected from the deep sea about 190 miles offshore Louisiana in the Gulf of Mexico during a 2010 mission by the NOAA Ship Pisces to study sperm whale feeding. It was presumably a juvenile male, just 14 cm long. (The first specimen was a female, some 40 cm long.)

NOAA’s Mark A. Grace, the paper’s senior author, who was part of that mission, uncovered the sample at his lab in 2013. Conferring with researchers at Tulane University, Grace realized he had another specimen of the enigmatic genus Mollisquama.

In fact, this new specimen may represent a new, second species. Features found on the Gulf of Mexico specimen that were not noted in the description of M. parini include a series of ventral abdominal photophore agglomerations and a modified dermal denticle surrounded by a radiating arrangement of denticles just posterior to the mouth. Teeth and vertebrae counts differ as well. Grace and his team are hoping to examine the M. parini holotype, which is housed at the Zoological Institute in St. Petersburg, Russia.

The news media had a field day coming up with headlines about this diminutive and distinctively un-sharklike shark:

“very rare and adorable”

“Chihuahua of the sea?”

“Jaws meets kangaroo”

“the cutest predator you’ll see all day”

“a bizarre mix of shark and kangaroo”

“Extremely rare shark is size of your iPhone”

As for the name itself, the original Pocket Shark was described by V. N. Dolganov of the Pacific Research Institute of Fisheries and Oceanography in Vladivostok. The generic name is derived from mollis, soft, and squama, scale, referring to its soft scales, which are apparently unique among sharks. The specific name honors ichthyologist Nikolai Vasil’evich Parin (1932-2012), Russian Academy of Sciences, an authority on the fauna of the Nazca submarine ridge (east of Chile), where it was collected.

Gobiesox milleri Briggs 1955

Tomorrow, 23 April, would have been the 99th birthday of one of our favorite ichthyologists, Robert Rush Miller. Born in 1916, he received his Ph.D. under the legendary Carl Hubbs at the University of Michigan in 1944. His academic and professional achievements include a long list of classic works on the taxonomy and zoogeography of the fishes of the American Southwest, Mexico and Central America, and Cenozoic fossil fishes of North America. He was an also an articulate conservationist. His 1961 study “Man and the Changing Fish Fauna of the American Southwest” warned of the decline of western North America’s unique fish fauna long before anyone cared about such things. His final work, Freshwater Fishes of Mexico, was posthumously published in 2005.

Details about Miller’s life and career can be found in this memorial tribute penned by his colleague and successor at the University of Michigan, Gerald R. Smith, upon Miller’s death in 2003.

It is no surprise that an ichthyologist of Miller’s stature should have several fish taxa named in his honor. The first was Gobiesox milleri Briggs 1955, a marine clingfish from Costa Rica. Miller was the first to note the unusual appearance of the holotype and kindly sent it to Briggs for examination.

Others (in chronological order) include:

Moxostoma austrinum milleri Robins & Raney 1957 — a subspecies of the Mexican Redhorse (a catostomid, or sucker), honoring Miller’s contributions to Middle American ichthyology

Xiphophorus milleri Rosen 1960 — a swordtail from Lago de Catemaco, Veracruz, Mexico (Miller collected the type)

Pomacentrus milleri Taylor 1964 — a damselfish, honoring Miller for a) collecting the type during the University of Michigan’s Arnhem Land Expedition (Northern Territory, Australia) in 1948; b) for his “excellently preserved” specimens from this expedition, including type of this species; and c) for making his field notes available for study

Cyprinodon salinus milleri LaBounty & Deacon 1972 — the Cottonball March Pupfish, a subspecies of the Salt Creek Pupfish that Miller himself described in 1943

Atherinella milleri (Bussing 1979) — a silverside from the Atlantic Slope of Colombia, Costa Rica and Honduras, honoring the “foremost authority” on Middle American fishes, who first recognized this species as new to science

Heterophallus milleri Radda 1987 — a livebearer (or poeciliid) from the Atlantic Slope of Mexico, honoring Miller as “one of the most prominent ichthyologists” (translation), with a special interest in cyprinodontiform fishes

Millerichthys Costa 1995 — monotypic genus of Mexican killifish, named for Miller, who described the type species, Rivilus robustus, with Hubbs in 1974

Cyprinodon bobmilleri Lozano-Vilano & Contreras-Balderas 1999 — a pupfish from the Atlantic Slope of Mexico, honored for his lifelong devotion to Mexican fishes and his “friendly support” of the authors’ studies

A fascinating aspect of Miller’s career were the collecting “vacations” he took with Carl Hubbs (1894-1979) to the deserts of eastern Nevada in the 1940s. Hubbs brought the entire family along — wife Laura and their three children, Frances, Clark and Earl. (Clark later became a prominent ichthyologist himself.)

The driving — there were few paved roads in the desert back then — was brutal. The constant jostling caused tires to blow, brakes to lock, and the battery to jar loose. Holes in the gas tank were patched with chewing gum. To keep the kids happy, Hubbs paid them an “allowance” for the fishes they caught. Each species was worth five cents. New species and subspecies were worth one dollar. And new genera and subgenera brought in the biggest bounty, $5 apiece!

Frances, Clark and Earl made a small fortune. During one 46-day “vacation” in 1934, they discovered over 20 new fishes, including Pit-Klamath lamprey (Entosphenus lethophagus), Alvord Chub (Siphateles alvordensis), Borax Lake Chub (S. boraxobius), White River Spinedace (Lepidomeda albivallis), Shorthead Sculpin (Cottus confusus), and Pit Sculpin (C. pitensis). The kids’ favorite fish must have been the Relict Dace (Relictus solitarius). For this new genus they each received a five dollar bill.

Four years later, the Hubbs family returned to the desert, this time with Dad’s graduate student, a young Bob Miller. The “vacation” lasted 62 days. Travel conditions had not improved. Bumpy roads made Frances seasick. Flat tires had to be changed every 3-5 days. One day the car got stuck in a dry river bed when the temperature was 55°C (131°F). Three fishes new to science were collected: Moapa Dace (Moapa coriacea), Big Spring Spinedace (Lepidomeda mollispinis pratensis), and the now extinct Las Vegas Dace (Rhinichthys deaconi).

Hubbs and Miller mapped pluvial lakes and streams that remained undiscovered by geologists for more than a decade. And they interviewed locals about the abundance and distribution of fishes in previous decades. One important discovery was that ranchers and Indians had been stocking exotic fishes in desert streams as far back as 1873.

Hubbs and Miller and other family members visited the desert many times over the ensuing years, discovering more new fishes and documenting the desert biota before the onrush of humans scarred the landscape forever.

Miller joined the Hubbs family permanently. By the time they returned to the desert in 1942, Frances Hubbs had become Mrs. Robert Rush Miller! Bob and Frances remained an inseparable research team until her death in 1987.

Pimelodella yuncensis Steindachner 1902

Last week we mentioned that sometimes the explanation of a fish’s name isn’t within the description of that particular species, but buried within introductory text that’s easily overlooked. Here’s another example, one that had us stumped for a week or so until we realized the explanation was staring at us all along.

Steindachner described this heptapterid catfish from the town of Pecasmayo along the Jequetepeque River basin of northern Peru in a multi-species work: Herpetologische und ichthyologische Ergebnisse einer Reise nach Südamerika, mit einer Einleitung von Therese Prinzessin von Bayern [Herpetological and ichthyological results of a trip to South America, with an introduction by Princess Theresa of Bavaria]. Denkschriften der Kaiserlichen Akademie der Wissenschaften in Wien, Mathematisch-Naturwissenschaftliche Classe. v. 72: 89-148, Pls. 1-6.

Usually, the suffix “–ensis” connotes a place, so we initially assumed that this catfish was named after a place called Yunce, or Yunca, or something of the sort. Maybe it was a village in Pecasmayo, or a tributary. But Steindachner’s description of the catfish (pages 135-136) offered not a clue. We poured over maps and atlases of Peru, looking for any place or geographic feature that began with the letters “yunc” but found none. We even looked into the biography of Princess Theresa of Bavaria (1850-1925), an amateur biologist and ethnologist who wrote about her travels to foreign lands and penned the introduction to Steindachner’s monograph. But we found nothing there.

Thanks to the Biodiversity Heritage Library, we not only had a PDF of Steindachner’s publication, but one in which the text was fully searchable. So we typed “Yunc” into Adobe Acrobat’s “search” field and, sure enough, found the answer on page 93 of Princess Theresa’s introduction. She described how she persuaded a young boy to jump into a brook, where he captured 10 characins (now identified as Bryconamericus peruanus) and two catfish. “The latter,” she wrote, “is now described under the name Pimelodella yuncensis, in memory of the highly civilized Indians of the Yunca tribe, who once populated the coastal areas [of northern Peru] and left many monuments and craft items” (translation).

Thanks, Princess!


Winteria_telescopa8 April 2015
Winteria telescopa Brauer 1901

With its massive, egg-shaped, forwardly directed eyes, it’s easy to see why the bathypelagic and circumglobal Binocular Fish, Winteria telescopa, received its specific name. What’s little-known about the genus — which contains just the one species — is how it received its generic name. As far as we can tell, most modern-day references do not explain the meaning of the name Winteria. Was it named after someone named Winter? If so, who? And why?

Perhaps the reason the meaning of the name is poorly known is that the German zoologist August Brauer (1863-1917), a pioneer in deep-sea ichthyology, did not explain its meaning in the brief (one-page), provisional description he published in 1901. He expanded on his description in the second volume of the book-length Die Tiefsee-Fische (The Deep-Sea Fishes) in 1908. Again, he did not explain the significance of the Winteria epithet. Scholars seeking an answer will find none if they restrict themselves to the sections describing the fish itself. But if they look to the introduction of Die Tiefsee-Fische, Brauer devotes a paragraph to praising and thanking Fritz Winter (1878-1917), the scientific illustrator on the Valdivia Expedition (1888-1899) to subantarctic seas:

The advantage of this publication over earlier ones is the exquisite color illustrations of new species and many previously known forms. This is the contribution of my friend and traveling companion Fritz Winter, who not only recorded the living colors of fishes immediately after their capture in a masterful manner, but also out of pure interest in science and the work itself was willing to complete the final versions of the sketches. His ability to excellently reflect the character of each deep-sea fish species in such a lifelike manner is due to his being a zoologist as well as an artist, resulting in the artistic figures shown here, which are unlike those in any previously published work. . . . It is therefore my great pleasure and duty to express to Fritz Winter my sincere thanks for his cooperation. [translated from the German with the help of Erwin Schraml]

Winter illustrated the species that would eventually be called Winteria telescopa. Here is a portfolio of many of his other stunning illustrations.

The son of a printer in Frankfurt, Winter was just 20 years old when joined the Valdivia Expedition, led by German marine biologist Carl Chun, as illustrator and photographer. After the expedition ended, Winter began his formal scientific education under Chun, but had to give it up to run the family print shop after his father passed away. Winter eventually returned to his studies, primarily on protozoa, but was not allowed to graduate because his classes under Chun counted for just two semester hours instead of the required six. Winter continued to provide scientific and technical illustrations, eventually joining the Faculty of Arts at the University of Marburg in 1911 (or 1912) and receiving an honorary doctoral degree. During World War I he served in the German Army on the Western Front in France and was severely wounded by a grenade in Champagne in 1917. Confined to what would be his deathbed, Winter received the Iron Cross for his military duty. He died the very next day.

Aphyosemion scherzi Falsehood & Deceit 1983

In 1983, a German aquarist named E. T. van Tomas reported that he had introduced a new Aphyosemion killifish from Gabon into the aquarium hobby. Tomas collected his specimens in a wooden trough used by Gabonese natives to make millet beer. Tomas published his note in DKG-Journal, the German-language publication of Deutsche Killifisch Gemeinschaft, the German Killifish Community. The species had been described, according to Tomas, a year earlier in the journal Fantasia by A. H. Falsehood and O. K. Deceit.

Sharp-eyed readers would have noticed that the publication date was April 1, 1983. They may also have picked up on other clues that the article was an April Fools’ hoax. “Fantasia” clearly means “fantasy.” “E. T. van Tomas” is a combination of E.T. The Extraterrestrial and a French movie phantom named Fantomas. The fish was collected in beer. (Is that why it was illustrated with a big smile on its face?) Who can trust the veracity of a description penned by guys named Falsehood and Deceit? (Although it should be noted that these English words may have looked like perfectly fine Anglo-Saxon surnames to some German readers.) And then there’s the specific epithet itself: scherz is German for hoax.

Apparently, the joke was lost on the famous German aquarist Günther Sterba (or one of his editors), who reportedly included Aphyosemion scherzi in a killifish checklist in a 1987 edition of his Süßwasserfische der Welt (Freshwater Fishes of the World). And there is one taxonomic website that treats scherzi as a misspelling of schioetzi, a valid species (now in Rhexipanchax) described in 1981.

The true identity of E. T. van Tomas has never been revealed.


Trichomycterus migrans25 March 2015
Trichomycterus migrans (Dahl 1960)

In 1960, Swedish ichthyologist George Dahl (1905-1979) described Pygidium (now Trichomycterus) migrans from the Guavabero River in the Southern Macarena Mountains of Colombia. He named the species migrans because of its impressive mass migrations (presumably spawning migrations), comprising upwards of 40,000 individuals. Dahl also described the catfish’s ability to escape their holding container and wriggle a short distance over rocks and back into the river. Since we’ve never seen his account mentioned in more recent literature, we thought it would be interesting to quote sections of it here:

March 14th, 1959. A big migration of [T. migrans] passed by, following very close to the river bank (here rocky). The school had a length of approx. 20 meters by a width of perhaps 40 cm., being on the whole very symmetrical, the terminations fore and aft softly rounded and the whole from some distance giving exactly the same impression as a very large anaconda swimming (though of course too long and narrow). With a single swift of a butterfly net, Dr. Ricardo Lozano caught more than ¾ gallon of the small fishes, that is to say, at least one thousand. At Dr. Lozan’s own estimate, with which I thoroughly agree, he removed about 50 cm. length from the “band” near the front end. This would mean that the number of specimens in the migratory school would total at least 40 times those caught. As they were swept up, the water in and around the net turned completely milky white, apparently from milt spilled by the fishes, and likewise the rock where they were landed. Lacking a microscope at the moment, the author was unable to investigate the true nature of this coloration. Most of the fishes were put into a large can with undiluted formaline, and this turned white too. Later on, when some specimens were dissected under the microscope, it was found that their gonads had burst and were practically empty. All the dissected specimens were males.

The “band” of fishes was almost compact. A few stragglers were observed, but only about a dozen. The opening formed by the sweep of the net was completely and almost instantly filled, and the migration continued without interruption. The small fishes swam at a good speed, and their swimming movements, though somewhat undulating, were not at all eel-like as in the foregoing species [Schultzichthys gracilis].

On February 24th, Dr. [Fred] Medem had observed a similar migration, though somewhat longer and narrower, and had taken specimens, which were found to belong to the same species.

Both migrations occurred when the river was rather swollen after heavy rains and fairly abundant rain-water was coming out of the small mountain breaks, which had earlier been dry for some time. It did not actually rain on the day of either migration, but had done so rather abundantly on two of three days before each migration.

Later that day, Dahl observed another migrating “band” of T. migrans:

A number of specimens from this band were captured and placed in about 10 cm. of water in a large aluminum container with completely vertical walls, 42 cm. high. There they continued to swim round the circular container, in closer vicinity of the wall, keeping up their formation and moving in unison. Some of the water was removed, so that there was a naked aluminum wall, 37 cm. high, above water-level. Some of the fishes began to climb this, as far as it was wet, where some water had been spilled. As soon as they reached the dry part near the edge, they turned back downward. Noting this, the author spilled some water down the wall of the container, so that it stayed wet all the way up. Now, several specimens climbed straight up to the edge, wriggled over it and fell down on the rocks; from there they climbed and wriggled out into the river, a distance of only some 60 cm. It is noteworthy that they always climbed the receptor on the side nearest the river; not a single specimen tried any other place on the wall, even when those were kept wet.

As soon as the uppermost 3-4 cm. of the wall dried, the fishes went up to the border of the wet part of the metal, and then they turned down again, even when the distance to the edge was less than their own length. Apparently, their climbing is not directed by sight but by some other sense, or else they are incapable of crossing the dry aluminum but none seemed to try.

Those that made it back to the river, Dahl noted, were almost always attacked and eaten by large Astyanax and other characids. In addition, schools of silvery characids “considerably smaller” than the catfishes appeared to follow them, presumably “to eat their spawn.”

Dahl’s account (and the illustration) appeared in his 1960 paper: Nematognathous fishes collected during the Macarena Expedition 1959. [Part I.]. Novedades Colombianas v. 1 (no. 5): 302-317.

The Coal Grunter, Hephaestus carbo

The Coal Grunter occurs in clear, fast-flowing freshwater streams in Northern Territory and Queensland, Australia. The meaning of its specific name is clearly understood. The meaning of its generic name is not.

The species was described by Australian zoologists James Douglas Ogilby (1853-1925) and Allan Riverstone McCulloch (1885-1925) as Therapon carbo in 1916. “Carbo” is Latin for coal (“a lump of coal,” according to the authors), and clearly refers to the species’ uniform blackish coloration, which is typical of larger adults.

British-born zoologist Charles Walter De Vis (1829-1915) proposed the genus Hepaestus for the Khaki (or Tully) Grunter, H. tullliensis, in 1884, but he did not explain the significance of the name. Hephaestus is the Greek god of blacksmiths, so our guess is that De Vis was alluding to the Khaki Grunter’s coloration, which, like H. carbo, was described as “uniform blackish.” In life, Khaki Grunters vary from grey-brown to a khaki green (hence the common name), but in alcohol they are an overall dark brown, including the fins.

Eleotris is a genus of sleeper gobies (Eleotridae) with a circumglobal distribution in tropical and subtropical regions. They are found in marine, brackish and fresh waters. What does Eleotris mean and why are they called “sleeper gobies?” No one knows for sure.

According to Cuvier and Valenciennes in the 12th volume of their Histoire Naturelle des Poissons (1837), the name is derived from a Greek name for an unidentified fish from the Nile. American ichthyologists Jordan and Gilbert (1883) state that the name derives from the Greek eleos, meaning bewildered. The common name “sleeper” appears to be an English translation of the common name “dormeur” used in the early 19th-century French colonies of South America. Cuvier and Valenciennes state that dormeurs are “usually lazy fish, which stand quietly in the mud or rock holes” (translated from the French).

Are “sleeper” and “bewildered” describing the same behavior? Maybe. The original meanings of fish names that date back to antiquities are difficult, if not impossible, to discern.

Sticharium clarkae George & Springer 1980 and Rhinichthys deaconi Miller 1984

The fields of ichthyology and conservation lost two more notable figures last week: famed marine biologist Eugenie Clark, popularly known as the “Shark Lady,” and influential desert-fish biologist James E. Deacon.

sharkladyClark studied the behavior, ecology and taxonomy of fishes, especially sharks, for over 50 years. She was a pioneer in the use of SCUBA for research purposes, and discovered that a milky liquid secreted by the Moses Sole (Pardachirus marmoratus) could serve as a shark repellent. Her 1951 book Lady with a Spear, which described her adventures in Micronesia and the Red Sea, was a best-seller. She later regretted the title of her book when she became a well-known champion of shark- and ocean-related conservation efforts. Perhaps because she was a woman doing what was perceived to be “man’s science,” she became the rare biologist-celebrity, featured in many popular magazine articles and television documentaries.

Four fishes have been named after Dr. Clark; surprisingly, none of them are sharks. The first was Sticharium clarkae George & Springer 1980, a clinid from southern New South Wales and Western Australia. The description was based on the senior author’s master’s thesis, which was completed under Clark’s supervision at the University of Maryland. Clark was honored for her “continued guidance and encouragement of the senior author.”

The three other fishes named after Clark, all from the Red Sea (her favorite place to dive), are:

  • Enneapterygius clarkae Holleman 1982, a threefin blenny (Tripterygiidae)
  • Atrobucca geniae Ben-Tuvia & Trewavas 1987, a drum or croaker (Sciaenidae)
  • Pteragogus clarkae Randall 2013, a wrasse (Labridae)

Dr. Clark died at the age of 92 on February 25, 2015, in Sarasota, Florida, from non-smoking lung cancer. National Geographic published this obituary illustrated with photographs by her friend and frequent collaborator, the famed underwater photographer David Doubilet.

deacon_smallWhile Eugenie Clark was SCUBA diving in the Red Sea, James E. Deacon was SCUBA diving in a far different habitat — Devil’s Hole of Nevada, USA, a water-filled cavern 90 miles west of Las Vegas that is home to the Devils Hole Pupfish (Cyprinodon diabolis). Fascinated by the incredulity of fishes living in the desert, Dr. Deacon became a champion of their conservation and a pioneer in environmental studies. In the 1970s, he testified in defense of the Devil’s Hole Pupfish during a legal fight over groundwater pumping that landed in the U.S. Supreme Court and resulted in a landmark decision favoring endangered species protection.

One fish has been named after Dr. Deacon, Rhinichthys deaconi, the Las Vegas Dace. Last collected in 1940, the Las Vegas dace probably survived until about 1955, when the amount of water withdrawn from the artesian basin beneath Las Vegas eliminated this minnow’s habitat for good. Its description in 1984 was an obituary of sorts when fellow desert-fish biologist Robert Rush Miller named it after Deacon, “whose concern about the conservation status of many fishes from the Southwest has aroused interest on their behalf and whose ecological studies have provided the necessary information needed to aid their survival.”

Dr. Deacon died February 23, 2015, at his home in Henderson, Nevada. Additional details about his life and career can be found in this obituary.

He was 80 years old.


Nosferatu_pdp25 February 2015
Nosferatu De la Maza-Benignos, Ornelas-García, Lozano-Vilano, García-Ramírez & Doadrio 2015

Nosferatu, a new genus of Meso-American cichlid, is named after an unlikely source—a silent German Expressionist horror film made in 1922 by director F. W. Murnau.

Writing in the April 2015 issue of Hydrobiologia, the authors propose the new genus for seven species formerly placed in Herichthys: Nosferatu pame (the type species), N. molango, N. pratinus, N. bartoni, N. labridens, N. pantostictus, and N. steindachneri.

The cichlids’ teeth inspired the unusual name. According to the authors, “The name refers to the pair of well-developed recurved fangs in the upper jaw present in all species of the genus, reminiscent of those in Murnau’s vampire Nosferatu.” [Actually, the vampire’s name is Orlok;
Nosferatu is a word, presumably of Romanian origin, that means vampire.]

This isn’t the first vampire to inspire a fish name. The goby Stonogobiops dracula Polunin & Lubbock 1977 from the Seychelles Islands was named after Bram Stoker’s famous creation for its peculiarly sharp white teeth. Likewise, the Burmese cyprinid Danionella dracula, described by Britz, Conway & Rüber in 2009, is named for the long, tooth-like fangs of males.

27 JUNE 2016 UPDATE: According to Říčan et al. (2016), the tooth morphology of Nosferatu is “ancestral for the Theraps-Paraneetroplus clade and also for Herichthys, where it is also present in the basal species of the H. cyanoguttatus group (the polymorphic species H. minckleyi)” and therefore cannot be used to diagnose a genus. Říčan et al. have driven a stake through the heart of Nosferatu, subsuming it into the synonymy of Herichthys.

Parakneria fortuita Penrith 1973

Last Friday was Friday the 13th, a day considered unlucky in Western superstition.

It’s also a day that played a role in the discovery of the Cubango Kneria, Parakneria fortuita, a gonorhynchiform fish found only in the Cutato River in Angola. According to the author:

The name reflects a number of fortuitous circumstances that were involved in collecting this species; camp was made at sunset at the river under the impression that it was the Okavango, when next morning the error was discovered it was impossible to go to the Okavango as the Cutato bridge was burnt down and heavy rain had closed the alternate route, leaving this [the Cutato River] as the only place to work [collect fishes] that day.

That day was 13 October 1972. A Friday.

Etheostoma boschungi Wall & Williams 1974

Herbert T. Boschung, professor emeritus of biology at The University of Alabama (UA), died Thursday, Feb. 5, in Tuscaloosa, Alabama.

Dr. Boschung’s primary field of research was the freshwater fishes of southeastern USA. His book, Fishes of Alabama, co-authored with Richard L. Mayden, is, in our opinion, one of the best “Fishes of …” books ever. Boschung was also the senior author of the Audubon Society’s Field Guide to North American Fishes.

Boschung was director of the Alabama Museum of Natural History from 1966-1978 and served as curator of fishes for UA’s Ichthyological Collection from 1966-1987. He was also director of the Alabama Marine Laboratory from 1966-1967.

Boschung was a life-long friend of Pulitzer Prize-winning myrmecologist and sociobiologist Edward O. Wilson; they worked together when they were both undergraduate biology majors at UA in the late 1940s. “We were a small band of student naturalists, known ever since as the Chermockians for our mentor Ralph Chermock, our professor of biology at The University of Alabama,” said Wilson upon Boschung’s passing.

Boschung introduced two new fish species to science: The Orangefin Shiner, Notropis ammophilus, of Alabama, Mississippi and Tennessee, described with Royal D. Suttkus in 1990; and the Vermilion Darter, Etheostoma chermocki, endemic to Jefferson Co., Alabama, described with Rick Mayden and Joe Tomelleri in 1992.

In 1974, Benjamin R. Wall, Jr., and James D. Williams named the Slackwater Darter of Alabama and Tennessee in Boschung’s honor, citing his contributions to ichthyology and “his inspiration and devotion to his students.”

Dr. Boschung was 89.

Peckoltia greedoi Armbruster, Werneke & Tan 2015

Last year we mentioned a couple of viviparous brotulas named after characters from The Hitchhiker’s Guide to the Galaxy. And there’s a genus of shark — Gollum Compagno 1973 — named for the antihero of Tolkien’s Lord of the Rings trilogy. Now there’s a brand new loricariid catfish named after a character from Star Wars.

According to the authors, Peckoltia greedoi is “Named for Greedo of Rodia, a bounty hunter killed by Han Solo in Chalmun’s Spaceport Cantina in the movie “Star Wars: Episode IV – A New Hope” (Lucasfilm, Twentieth Century Fox, 1977) with whom this species shares a remarkable resemblance.”

Check out the description, which includes photos of the catfish. Do you see a resemblance?

May the force fish be with you!

Steindachneridion Eigenmann & Eigenmann 1919

When Carl Eigenmann and his wife Rosa proposed this name, you can tell they were annoyed by having to do so.

Neotropical Ichthyology 10(2): 313-327.

In 1888, the Eigenmanns created the genus Steindachneria for three large pimelodid catfishes from eastern Brazil. The name honors Austrian ichthyologist Franz Steindachner. Shortly after its publication, the Eigenmanns learned that Goode and Bean had proposed the same name for a genus of merlucciids (also honoring Steindachner) just three months earlier. The Eigenmanns believed Goode and Brown’s name — a short diagnosis with no types assigned — was a nomen nudum and therefore did not qualify as a valid name. So they wrote an “apologetic note” to Goode calling his attention to this fact. In a return letter Goode appeared to agree, saying that their Steindachneria “has never been published, though the diagnosis of the genus has been lying in manuscript for nearly two years. So we will change the name. It is not of the least consequence.”

But Goode and Bean never changed the name. When their manuscript was finally published — as the book-length “Oceanic Ichthyology” in 1896 — Steindachneria was retained. Believing their Steindacheria had priority, Eigenmann proposed a replacement for Goode and Bean’s name, renaming it Steindachnerella in 1897.

Eventually, David Starr Jordan, the doyen of American ichthyology, stepped in to settle the affair. He advised the Eigenmanns that under the present rules of nomenclature a “nomen seminudus holds” and that they should rename their catfish genus. So in 1919 Mr. and Mrs. Eigenmann did just that. You can sense their annoyance in how they worded their proposal:

Reluctantly and with effort we submit to changing opinion, realizing that it is a long time since we began to give names to the fresh water fishes of South America. Therefore, under the name Steindachneridion we rebaptize those catfish which, for thirty-one years have been nozing around on the river bottoms just north of Rio Janeiro under the improper appelation Steindachneria.

So there.

Torquigener: the builder of “mystery circles” with the mysterious name

It was the underwater equivalent of crop circles. For the past 20 years, strange circular depressions have been found on sandy bottoms at depths from 10 to 27 m along the south coast of Amami-oshima Island of the Ryukyu Islands of Japan. These ‘‘mystery circles’’ are large (~ 2 m in diameter), and are characterized by double edges and radiating troughs, giving them a spoke-like appearance. Their appearance long puzzled SCUBA divers until three years ago, when an underwater photographer named Yoji Okata observed a pufferfish of the genus Torquigener in the act of building one. Subsequent observations revealed that the circles are created by males, which excavate a nest in the center of the depression, and then dig “radially aligned peaks and valleys” around it. The males also create irregular patterns in the next comprising fine sand particles. Females are apparently attracted to these particles, and the ridges and valleys around the nest work to gather fine sand to the nest.

The behavior was reported in the scientific literature in 2013, but the puffer, which represents a new species, has only recently been described and given a name, T. albomaculosus. The specific translates as albus (=white) and maculatus (=spotted), referring to the many white spots on its body.

As far is known, T. albomaculosus is the only fish that builds large geometric circles on sandy bottoms.

When we checked the Wikipedia entry (as of 20 Jan. 2015) for the genus Torquigener, it contained a sentence that appeared to challenge the above claim: “Their name refers to their ability to build circular structures on sandy sea bottom (torquis + gener).”

Since the genus dates to 1930, does this mean the puffer’s mysterious circle-building behavior has actually been known for over 80 years?

We checked Whitley’s description of the genus and can report that Wikipedia has the etymology of the name wrong. But we’re not sure what the name means. In this regard, ichthyologist Gilbert Percy Whitley (1903-1975) was the Australian equivalent of Edward Drinker Cope. Both appeared to take a perverse delight in coining enigmatic names with no explicit or easily discernible meaning or etymology. Torquigener is a case in point.

In addition to the explanation now posited on Wikipedia, FishBase offers its own: from the Latin torquere = to twist + Latin, generare = birth, race. We suspect that is wrong as well.

Let’s review Whitley’s brief description of the genus. Here it is in its entirety:

A row of papillae before the gill-openings. Chin prominent, deep, plicated. Nostrils in the form of a rounded papilla with two perforations. Nine or ten dorsal rays. Dorsal and anal fins elevated, acute. Caudal fin rounded but with the outer rays slightly produced. Lateral line system well developed. A fold on each side of body. Skin of back, sides, and belly with spaced spines.

Our guess is that Torquigener is derived from the Latin torquatus, which means “adorned with a necklace or collar,” and that the –gener part of the name is derived from gena or genio-, meaning cheek or chin. If this translation is correct, then maybe the name is referring to the first attribute that Whitley mentioned in his description: “A row of papillae before the gill-openings.” Or maybe the name refers to the second-mentioned character, the “plicated” (or pleated) chin. Perhaps its relevant to note that the Australian common name of the type species, T. tuberculiferus, is “fringe-gill toadfish.”

Whatever the explanation, the name clearly does not refer to nest-building behavior, which was unknown at the time.

Dinotopterus loweae (Jackson 1959) and Rhinodoras thomersoni Taphorn & Lilyestrom 1984

This week, we mourn the recent passing of two notable figures in ichthyology, Rosemary Lowe-McConnell and Jamie E. Thomerson.

Rosemary Lowe-McConnell was a pioneer in the study of tropical fish ecology. Her work, spanning some 50 years, contributed greatly to our understanding of the ecology, zoogeography, phenology, evolution, and taxonomy of African and South American freshwater fishes. Her specialty was cichlids, where she helped to raise awareness of the ecological damage being inflicted on the fish stocks of Lake Victoria in East Africa.mcconnell_3158476b

In 1959, the African clariid catfish Dinotopterus loweae was named in her honor, for her “single-handed” survey of the Tilapia of Lake Malawi (Nyasa), which “drew attention to the large number of clariid species existing in the lake.” Two South American characins also bear her name: Hyphessobrycon loweae Costa & Géry 1994 and Moenkhausia loweae Géry 1992 (she collected the types of both). She also collected the type of Crenicichla rosemariae Kullander 1997, a pike cichlid from Brazil. Kullander called her a “persistent inspiratrix to students of tropical fish ecology.” Her nickname Ro is alluded to in the name of the cetopsid catfish Cetopsidium roae Vari, Ferraris & de Pinna 2005; she had collected all known specimens of the fish and was honored for her contributions to the knowledge of the fishes of Guyana and many other regions on the world.

Dr. Lowe-McConnell died on 22 December 2014. She was 93. You can read a detailed obituary here. A 1994 overview of her life and work is available here.

The same day we learned of Dr. Lowe-McConnell’s death, we learned of Dr. Thomerson’s.

Jamie E. Thomerson received his Ph.D. at Tulane University in New Orleans in 1965. He was recognized as an expert on killifishes, making many trips to Venezuela, Belize, Colombia, ThomersonGuyana and Peru, from where he described or co-described 16 new species and two new genera. In addition, he and his students at Southern Illinois University studied the fish populations of the small streams of southern Illinois, Missouri and Indiana. With David Greenfield he co-authored the book Fishes of the Continental Waters of Belize (1997).

In 1984, the doradid catfish Rhinodoras thomersoni of Venezuela and Colombia was named in his honor. Dr. Thomerson introduced the senior author (Donald C. Taphorn) to the study of fishes and led Taphorn’s first trip to South America. He also led the expedition that collected the type.

Dr. Thomerson passed away on 4 January 2015 in Austin, Texas. He was 79.

Platycephalus australis Imamura 2015

Today we celebrate the New Year with the first new fish species of 2015 —Platycephalus australis, a new Flathead from Australia. Here’s the ref:

Imamura, H. 2015. Taxonomic revision of the flathead fish genus Platycephalus Bloch, 1785 (Teleostei: Platycephalidae) from Australia, with description of a new species. Zootaxa, 3904 (2): 151–207.

The epithet australis means “southern” and refers to its type locality at Exmouth Gulf in northern Australia.

An average of 350 new fish species have been described each year over the past 20 years. In 2014, according to our friends at Welt der Fische / World of Fishes, 356 new fish species and 19 new genera were added to Earth’s catalog of life. That’s just over one new name every week.

One down, 364+ to go!

Happy New Year!
