The deepest known fish in the ocean

The deepest known fish in the ocean

The recently discovered Mariana snailfish has been named the deepest known fish in the ocean.  It thrives at depths of around 8,000 meters (26,000 feet) along the Mariana Trench near Guam. It is a small scaleless and translucent fish.  In a series of dives in 2014 and 2017, a small team of researchers from the U.S. and U.K. dropped special traps into the depths of the Mariana Trench in the Pacific Ocean in order to catch the fish at the extreme depths.  The traps—equipped with specialist cameras—emerged with incredible footage of the new species, as well as 37 other fish over the courseRead More

Aquatic biologist Jeff Simmons, who helped discover the fish, named it after the clean, clear waters where it lives, in the The Tennessee River system—the most biologically diverse in North America.  The mere existence of the Tennessee Logperch says something positive about the water quality in this part of the Tennessee Valley—it’s good.   Simmons and colleagues named the new species apina, which in Greek describes things that are clean, or without dirt, referring to the silt-free substrates that it requires.  The fish has been noted as far back as 1971, though it had been previously recognized as a population ofRead More

A Stunning Dartfish from Japan & Philippines, Named by School Students

A Stunning Dartfish from Japan & Philippines, Named by School Students

Fish, New Species November 27, 2017 at 9:10 am

Kaguya’s dartfish was described from two specimens, one from Japan and another from the Philippines, both collected relatively deep at 24 meters (137 feet) in Japan and 55 meters (180 feet) in the Philippines.   The fish has been known to Japanese divers and researchers since 1994 but is only now formally described. The fish’s name was selected by school students at a climate change workshop at the University of Sydney, from the anime film The Tale of the Princess Kaguya.  The name alludes to the yellow markings of this fish’s dorsal fin, which are said to resemble the graphics from aRead More

The newly discovered species include more than 30 species new to science, and likely endemic to Guyana, including six species of fish, three plants, a tarantula, a frog, a snake, some dragonflies, plants and beetles.  The month long survey was conducted in Kaieteur National Park (KNP) and the Kaieteur Plateau in Guyana.

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.

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 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

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.
