Researchers have identified a new deep water goby in the Caribbean.  At the time of its discovery, from a submarine, researchers recorded footage of a lionfish cornering, attacking and eating the new species. The new species described in the paper has a bright orange stripe down its spine and schools together in masses of about 100 fish—starkly different behavior from most gobies that hide as individuals in holes or cracks in the reef, making the new species an easy target for lionfish attacks.  The good news is the goby species being eaten by the lionfish appears to be abundant throughoutRead More

In the latest reef survey of the marine RAP (Rapid Assessment Program) in the Lau Seascape in the Fijian Archipelago, researchers attempted to photograph as many reef fish species as possible, particularly those that are rare or appear new.  527 species over the 11-day expedition, with six to nine new or potentially new species, as well as several previously known but still undescribed species.  Most of the potentially new fish species were small gobies, including a number of coral dwarf gobies in the genera Trimma and Eviota, as well as a sand goby in the genus Grallenia.  There was also a beautiful damselfish, believed toRead More

In a paper released last month, a team of Chilean researchers revealed the first images of what may be at least six new reef-dwelling species.  The finds include a butterflyfish with vertical black bars and a wrasse sporting eye-catching orange stripes.  In April technical divers with the California Academy of Sciences were able to capture a specimen of one of the new species — a damselfish with yellow fins — which will soon receive a scientific name (see reports of the expedition, with descriptions of other new species).  These are the first video observations from this region of the deep-dwelling fishesRead More

An entirely new genus is described from the mesophotic reefs of Indonesia, just the second genus to join the slopefish family.  Cymatognathus aureolateralis, the Wavy Jaw Slopefish, was discovered by chance at a local fish market in Northern Sulawesi, where it had been collected as bycatch. Our only glimpse at this fish in life comes courtesy of a single, tantalizing image captured at a depth of 200 meters as part of a coelacanth survey.

A re-evaluation of the armoured catfish species of Hypostomus in the Rio Jaguaribe, north-eastern Brazil, was prompted by the discovery of specimens with pale spots on a dark background collected from that basin c. 1936 and deposited at the Academy of Natural Sciences of Philadelphia. Recent field collections in the Rio Jarguaribe basin confirmed the presence of the pale-spotted specimens and its distinctiveness as a new species.

Scientists at the University of Washington, Texas A&M University and the Western Australian Museum discovered the new genus and species of clingfish after stumbling upon a specimen preserved in a jar dating back to the 1970s, of the Western Australian Museum in Welshpool, Australia. The teensy translucent fish is just a few inches long, but it sports between 1,800 and 2,300 teeth in its duckbill-like mouth. The new species was trawled from sponge and algae reefs between 30–40 meters in depth offshore from Fremantle, Western Australia.
