My postdoc was spent looking at hybridization between humpback (Gila cypha, above) and roundtail (G. robusta) chub in the Colorado river system (see here for a publication that stemmed from that – perhaps sometime I’ll post on that work). My fieldwork was at the confluence of the Colorado and Little Colorado rivers where we’d capture,…

Sometime in the Devonian

Back in October, Afarensis introduced us to the Douc langur (Pygathrix nemaeus), and noted that the species was comprised of three subspecies, one of which was the grey-shanked douc langur (P. n. cinerea). That subspecies is one of the 25 rarest primates in the world and fewer that 1000 individuals were believed to exist in…

Good news for Desert Pupfish

My post-doctoral research was in hybridization among endangered desert fishes here in the American Southwest, so it has made me happy to read that a new population of the endangered Desert pupfish (Cyprinodon macularius, above) has mysteriously appeared in man-made research ponds in Salton Sea, California. Many of the over 1000 specimens are juveniles, which…

How many catfish are there?

The old story goes that JBS Haldane felt that God had an inordinate fondness for beetles. It also seems he likes catfish. CJ Ferraris has produced a checklist of fossil and living catfishes and estimated that there are 3093 valid species in 478 genera (and 36 families). Of these 72 species are known solely from…

What was lost, has been found

There has been some blogospheric notice of the Conservation International survey in Surimane which has found 24 new species. Other good news is that the previously thought to be extinct dwarf suckermouth catfish (Harttiella crassicauda, above) has been re-discovered. The species – which reaches a size of about five centimeters – had last been spotted…

AP is reporting: Female sharks can fertilize their own eggs and give birth without sperm from males, according to a new study of the asexual reproduction of a hammerhead in a U.S. zoo. The joint Northern Ireland-U.S. research, being published Wednesday in the Royal Society’s peer-reviewed Biology Letter journal, analyzed the DNA of a shark…

The return of the catfish from hell

So I noticed that visits to the blog ramped up after 2100 EST tonight with traffic increasing ten-fold. And the reason? Grey’s Anatomy mentioned this little blighter.

Impressive teeth

Over at Fark.com they are discussing this photo of a Goliath tigerfish (Hydrocynus goliath) which occurs in the Congo River basin, the Lualaba River, Lake Upemba and Lake Tanganyika.

Pretty fishies

Four new species of Loricariid catfish have been described from the upper Río Orinoco of southern Venezuela: (A) Hypancistrus inspector, (B) H. lunaorum, (C) H. furunculus, and (D) H. debilittera, Full details are in Armbruster et al. (2007) “Four New Hypancistrus (Siluriformes: Loricariidae) from Amazonas, Venezuela” Copeia 2006(1): 62-79 (link). Experts at Planet Catfish claim…
