Not just another tequila sunrise

Not just another tequila sunrise

A bright fairy basslet known from Micronesia is now described.  This gorgeous, brightly coloured little fish is found in the Ogasawara Islands and the Marianas Islands in the western Pacific Ocean.  Divers have typically encountered this species in depths below 40 meters, and, no doubt, it can be expected quite a bit further down into the mesophotic zone.  See other anthias discovered in recent years.  See video of the Cave anthias in its habitat.  The species name for the new little fish alludes to the bright coloured cocktail tequila sunrise.

Little Frogfish “Rediscovered” After More Than a Century

While only four individuals of this fish has been reported since first described, this small frogfish has actually been hiding in plain sight all along, with countless photographs posted on the internet.   The rarity of Nudiantennarius was really nothing more than a case of mistaken identity.  As it turns out, N. subteres is identical to a fish that divers have been photographing across the Coral Triangle for years. It has been referred to variously as the Ocellated Frogfish or the Lembeh Frogfish, after the Lembeh Straits, where the species is particularly abundant.   Authors reexamined the 1909 specimen, along with a handful of others that matched up withRead More

This fish, with its unique dorsal fin was first spotted in captivity in 2016, a specimen purchased from a local aquarium in Belgium.  The new species of pygmy sandperch was discovered on deep rubble zones at Cebu, Philippines.  Other species of sandperch from the Philippines have been described recently, which were also found first in markets (see Five New Colorful Species of Sandperch, Sept 2017) .

The brilliant wrasse is completely devoid of any stripes or spots.  It is a very red fish.  At the depth it’s collected where red appears black, so would be almost impossible to see in its natural habitat.

The Parapercis sandperches are one of the most highly diverse groups of reef-associated fishes, with roughly 81 species having been recorded (and many more yet waiting scientific description). Now, we can add another five species to the list.  Two of the species fish were found in markets.

The small, bioluminescent, long nosed shark was found nearly 1,000 feet below the Pacific Ocean off the coast of Hawaii’s northwestern islands.  First discovered 17 years ago, initial findings were published in February before the news was widely circulated by the corresponding researchers’ institutions this month.   See also other lanternsharks recently discovered.

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.
