| Bidenichthys okamotoi | |
Bidenichthys okamotoi is a species of fish in the family Bythitidae. It is found at the Koko Seamount in the central-northern Pacific Ocean. [1]
The species is named after the collector of the two type specimens, Dr. Makoto Okamoto, of the Seikai National Fisheries Research Institute, in honor of his numerous contributions to Pacific ichthyology. [2]
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface, and thus is not an island, islet, or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height. They are defined by oceanographers as independent features that rise to at least 1,000 m (3,281 ft) above the seafloor, characteristically of conical form. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat-top seamounts are called "guyots" or "tablemounts".
The viviparous brotulas form a family, the Bythitidae, of ophidiiform fishes. They are known as viviparous brotulas as they generally bear live young, although there are indications that some species do not. They are generally infrequently seen, somewhat tadpole-like in overall shape and mostly about 5–10 cm (2–4 in) in length, but some species grow far larger and may surpass 60 cm (2 ft).
Koko Guyot is a 48.1-million-year-old guyot, a type of underwater volcano with a flat top, which lies near the southern end of the Emperor seamounts, about 200 km (124 mi) north of the "bend" in the volcanic Hawaiian-Emperor seamount chain. Pillow lava has been sampled on the north west flank of Koko Seamount, and the oldest dated lava is 40 million years old. Seismic studies indicate that it is built on a 9 km (6 mi) thick portion of the Pacific Plate. The oldest rock from the north side of Koko Seamount is dated at 52.6 and the south side of Koko at 50.4 million years ago. To the southeast of the bend is Kimmei Seamount at 47.9 million years ago and southeast of it, Daikakuji at 46.7.
Acarobythites larsonae, or Larson's cusk, is a species of viviparous brotula fish only known from reefs off the coast of the Northern Territory, Australia. This species grows to a length of 2.5 centimetres (0.98 in) SL. This species is the only known member of genus Acarobythites. The specific name and common name both honour the curator of fishes at the Museum and Art Gallery of the Northern Territory in Darwin, Northern Territory, Helen Larson who sent speciemsn of fish, especially Ophidiiformes, to the describer Yoshiko Machida for him to study.
Bidenichthys is a genus of viviparous brotulas.
Brosmophyciops pautzkei, the slimy cuskeel or free-tailed reef brotula, is a species of viviparous brotulas found in tropical reefs of the Indian and Pacific Oceans. This species grows to 7 cm (2.8 in) total length. This species is the only known member of its genus. The specific name honours Clarence F. Pautzke, who was a former student of the describer of this species who went on to become the chief biologist in the Department of Game of Washington state and who was present on Bikini Atoll in 1946 and 1947 when the type specimen was collected.
The Southern pygmy blindfish is a species of viviparous brotula, the only known member of its genus, found in the waters of the Indian Ocean off the coast of western Australia. This species grows to a length of 6 centimetres (2.4 in) SL. The specific name honours Martin F. Gomon, who was the senior curator of fishes at the Museum of Victoria in Melbourne, for his numerous contributions to the ichthyology of Australia.
Ematops randalli is a species of viviparous brotula found in the Pacific Ocean around Samoa and Vanuatu where it inhabits reef environments. This species grows to a length of 4.2 centimetres (1.7 in) SL. The specific name honours the American ichthyologist John E. Randall of the Bishop Museum who assisted in the collection of the type.
Majungaichthys is a genus of viviparous brotulas native to the western Indian Ocean. The generic name refers to Majunga in Madagascar where the type was collected.
Mascarenichthys is a genus of viviparous brotulas. They have mostly been collected from the region of Mascarene Plateau in the Indian Ocean and this is referred to in their generic name.
Ogilbichthys is a genus of viviparous brotulas found in the central-western Atlantic Ocean and the Caribbean Sea. The generic name refers to the resemblance of these fish to those in the genus Ogilbia, a name honours the Australian naturalist James Douglas Ogilby (1853-1925), combined with ichthys which means "fish" in Greek.
Zephyrichthys barryi is a species of viviparous brotula found in the Indian Ocean waters around western Australia. This species grows to a length of 5.9 centimetres (2.3 in) SL. This species is the only known member of its genus. The etymology of the name is that the generic name is a compound of zephrys which is Greek for the west wind and refers to the species western Australian range and ichthys, "fish". The specific name honours in the ichthyologist J. Barry Hutchins of the Western Australian Museum (WAM) for his contribution to the knowledge of Australian fishes and for allowing the describers of Z. barryi access to the museum's collections.
Bassogigas gillii is a species of cusk-eel found in the Indian, Pacific Ocean, and Atlantic Oceans at depths of from 637 to 2,239 metres.
Adelosebastes is a monotypic genus of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. The only species in this genus is Adelosebastes latens, the Aleutian scorpionfish. It is found in the northern Pacific Ocean.
Hozukius is a genus of marine ray-finned fishes belonging to the subfamily Sebastinae within the family Scorpaenidae. They are native to the northwestern Pacific Ocean.
Bidenichthys beeblebroxi is a species of common reef fish of the family Bythitidae, and one of three species in the genus Bidenichthys. The species is found in the coastal waters off North Island and northern South Island, New Zealand. It is a common, uniformly gray-brown fish, ranging from SL 6.5–9.5 centimetres long in one study, found in holes beneath rocks and boulders in kelp forest and other reef habitats from the surface down to depths of 30 metres (98 ft). The species was described by Paulin in 1995.
Bidenichthys capensis, the freetail brotula, is an uncommon South African fish of the family Bythitidae, and one of three species, and the type species, of the genus Bidenichthys. The species is found in intertidal zones and rocky tidepools ranging from East London to the Cape of Good Hope, South Africa. It grows up to 90 mm long TL.
The silver trumpter is a species of marine ray-finned fish belonging to the family Latridae, the trumpeters. It has only been recorded from the Foundation Seamounts in the South Pacific Ocean.
Mascarenichthys heemstrai is a ray-finned fish species from the family of Bythitidae in the genus of Mascarenichthys. The scientific name of the species was first published in 2007 by Schwarzhans & Møller, It was named after Phil Heemstra, a notable ichthyologist.
