Bassozetus is a genus of cusk-eels found in Atlantic, Indian and Pacific Ocean. [2]
There are currently 13 recognized species in this genus:
Ophidiiformes is an order of ray-finned fish that includes the cusk-eels, pearlfishes, viviparous brotulas, and others. Members of this order have small heads and long slender bodies. They have either smooth scales or no scales, a long dorsal fin and an anal fin that typically runs into the caudal fin. They mostly come from the tropics and subtropics, and live in both freshwater and marine habitats, including abyssal depths. They have adopted a range of feeding methods and lifestyles, including parasitism. The majority are egg-laying, but some are viviparous.
The cusk-eel family, Ophidiidae, is a group of marine boney fishes in the order Ophidiiformes. The scientific name is from the Greek ophis meaning "snake", and refers to their eel-like appearance. True eels, however, diverged from other ray-finned fish during the Jurassic, while cusk-eels are part of the Percomorpha clade, along with tuna, perch, seahorses, and others. Unlike true eels of the order Anguilliformes, cusk-eels have ventral fins that are developed into a forked barbel-like organ below the mouth. In the true eels by contrast, the ventral fins are never well-developed and usually missing entirely.
Coelorinchus is a genus of rattails.
Coryphaenoides is a genus of rattails which is found in all oceans of the world. They are found in deep waters and C. yaquinae, recorded to 7,012 m (23,005 ft), is the only member in the family known from the hadal zone.
Hymenocephalus is a genus of rattails.
Abyssobrotula galatheae, is a species of cusk eel in the family Ophidiidae. It is the deepest-living fish known; one specimen, trawled from a depth of 8,370 m (27,460 ft) in the Puerto Rico Trench in 1970, holds the record for the deepest fish ever captured. Although generally recognized, some have suggested that the record-breaking individual might have been caught with a non-closing net and therefore perhaps caught shallower.
Abyssobrotula is a genus of cusk eel in the family Ophidiidae.
Epigonus is a genus of fish in the family Epigonidae found in the Atlantic, Indian and Pacific Ocean. The genus was erected by Constantine Samuel Rafinesque in 1810.
Barathronus is a genus of deep-sea fish that are placed in the family Aphyonidae or family Bythitidae (brotulas), depending on the source.
Bellottia is a genus of viviparous brotulas which is found in the subtropical waters of the North Atlantic, the Mediterranean Sea and the Indo-Pacific.
Timorichthys is a genus of viviparous brotulas so far known from the East China Sea and the Timor Sea.
The bony-eared assfish is a bathypelagic species of cusk-eel found in tropical and sub-tropical oceans at depths of from 1,171 to 4,415 metres. It has been found as far north as Queen Charlotte Sound off British Columbia's coast. This species grows to a length of 37.5 centimetres (14.8 in) SL. It is the only known member of its genus Acanthonus.
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.
Bassogigas is a genus of cusk eel from the subfamily Neobythitinae, part of the family Ophidiidae. The generic name "Bassogigas" comes from a combination of two Latin words: bassus, which means "deep" and gigas which means "giant". The species are found in the Indo-Pacific and western Atlantic Ocean.
Neobythites is a genus of cusk-eels.
Otophidium is a genus of cusk-eels, part of the subfamily Ophidiinae in the family Ophidiidae. They are found in the western Atlantic and eastern Pacific.
Sirembo is a genus of cusk-eels of the subfamily Neobythitinae, family Ophidiidae, which are found in the Indian and Pacific Oceans. The species in this genus have a rather robust body with the dorsal fin originating over vertebrae 1–5. The head and bod are completely covered in scales, they have large eyes which are almost equal in diameter to the length of snout, the pelvic fins have two rays which are joined together within an area of tough skin, They have a short spine on the operculum which does not extend to the posterior edge of the head. Their coloration is variable but almost all species have black spots or eyespots on the dorsal fin, sometimes both, while the middle part of the anal fin frequently has a black band. The body and/or head are marked with diagonal or horizontal dark stripes or horizontal rows of quite large dusky spots.
Oxycheilinus is a genus of fish in the family Labridae found in the Indian and Pacific Ocean.
Terelabrus is a genus of fish in the family Labridae found in the Indian and Pacific Ocean.
Brotulotaenia brevicauda is a benthopelagic marine fish species in the family Ophidiidae. This totally black fish is usually found in the Atlantic Ocean but it has also been reported in the Indian. B. brevicauda lives in deep water and grows up to 32 cm in length. It is also occasionally known as the Short-tail cusk-eel.
