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

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

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.

A new hermit crab species can live in a walking coral’s cavity in a symbiotic relationship, replacing the usual marine worm partner.  It is the only known hermit crab species to partner with a living coral.  The newly discovered crab was identified by accident, after finding a one inside a preserved walking coral.  Specimens of the new species were collected in the Oshima Strait of Japan at depths of 60-80 meters, and the species had been previously reported from a shallower bay in Japan at 30 meters.

A new butterflyfish is described from deep reefs in the Philippines.  Researchers for the California Academy of Sciences realized only muc later that the had a specimen of the same species in a jar, undiscovered, for years. The genus, Roa, with four described species, has as many undescribed species.  The authors name the new fish to honor Donald Rumsfeld and his famous quote as it relates to the challenge in taxonomy in identifying new species.  Referring to the uncertainties of war, Rumsfeld states “there are known knowns; there are things we know we know. We also know there are known unknowns;Read More

First record of an invasive species preying on an undiscovered native species

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

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.

Both new species were found in mesophotic reefs in the Caribbean.  Two specimens of the Pygmy Jawfish, a new species and genus,  were found 250m deep off Cuzumel.  It is only inch in length.  It is described as a new genus.   Despite occurring beyond the reach of most divers and collectors, the Curaçao Jawfish was already been made available to aquarists, collected by the Curaçao-based submersible Curasub.

A diving expedition off Easter Island, 60–150 meters beneath the surface (the “twilight zone”), reveal new species of fish and invertebrates.  In collaboration with SUBELAB Pontificia Universidad Católica de Chile, a scientific team from the California Academy of Sciences became the first divers to study mesophotic ecosystems off Rapa Nui.  An orange colored sea biscuit, and four fish collected are almost certainly new species.  California Academy of Sciences Ichthyology Curator Luis Rocha plans to give the fish all Rapa Nui names in honor of the local culture.

The species was discovered 300 feet deep, on June 5, 2016, during a research trip to Kure, the world’s northernmost atoll.  The species name and description was published Dec 2016. “It is the one fish known to live only within the Papahānaumokuākea Marine National Monument, a pristine expanse of coral reefs and seamounts home to millions of seabirds, endangered turtles, endangered monk seals, and more than 7,000 species. So scientists thought it only fitting to name this fish after President Barack Obama, who dramatically expanded Papahānaumokuākea, creating the largest swath of protected land or water on Earth, an area roughly twice the size ofRead More

Thanks to advances in submersible technology, recent exploration of mesophotic (AKA twilight zone) Caribbean reefs have yielded nine new deep-water goby species and a reclassification of the Nes subgroup of gobies.   All the gobies hail from deepwater, mesophotic Caribbean reefs.  The research team documented and captured specimens using manned submersibles such as the Johnson Sea-Link I and II submersibles and the Curasub.

The new species has a disproportionately large head and multiple rows of recurved canine teeth in each jaw, which is why the research team chose the common Godzilla goby. This deep water Goby adds to another identified last year and nine new goby species identified last month.  As part of The Smithsonian Deep Reef Observation Project (DROP), the new goby fish species was discovered in the southern Caribbean. Living at depths greater than conventional SCUBA divers can access, yet too shallow to be of interest for deep-diving submersibles, the fish will now be known under the common name of the Godzilla goby.

‘Luzonichthys seaver is a new species of splitfin anthias that has just been described from two specimens collected in Pohnpei Micronesia. The splitfin anthias are an uncommon group of fishes in the marine aquarium hobby whose number of recognized species just grew to seven with the induction of Luzonichthys seaver.
