Atractodenchelys is a genus of eels in the cutthroat eel family, Synaphobranchidae.
There are currently two recognized species in this genus: [1]
The superorder Elopomorpha contains a variety of types of fishes that range from typical silvery-colored species, such as the tarpons and ladyfishes of the Elopiformes and the bonefishes of the Albuliformes, to the long and slender, smooth-bodied eels of the Anguilliformes. The one characteristic uniting this group of fishes is they all have leptocephalus larvae, which are unique to the Elopomorpha. No other fishes have this type of larvae.
Saccopharynx is a genus of deep-sea eels with large mouths, distensible stomachs and long, scaleless bodies. Commonly, these fish are called gulpers or gulper eels. It is the only genus in the family Saccopharyngidae, and is part of the derived lineage of the "saccopharyngiforms," which includes other mid-water eel species. The name is from Latin saccus meaning "sack" and Greek φάρυγξ, pharynx.
Ilyophis is a genus of eels in the cutthroat eel family Synaphobranchidae.
Monognathus, or onejaw, is the only genus of the family Monognathidae of deep-sea eels. The name comes from the Greek monos meaning “one” and gnathos meaning “jaw”, a reference to the large mouth in comparison with the rest of the fish, and also the absence of an upper jaw.
Lucifuga is a genus of viviparous brotulas. Most of the species are native to caves and sinkholes in Cuba and the Bahamas; L. inopinata from deep water off the Galápagos Islands is the only exception. The four species rated by the IUCN are all considered vulnerable. The largest species in the genus reaches about 15 cm (5.9 in) in length.
Saccogaster is a genus of viviparous brotulas. They are found in the western Atlantic and Indo-Pacific.
Chlopsis is a genus of eels of the family Chlopsidae.
Dysomma is a genus of eels in the cutthroat eel family Synaphobranchidae.
Haptenchelys is a genus of deep-water eel in the family Synaphobranchidae. It contains two species. It is found in the Atlantic Ocean and Pacific Ocean at depths of 2,121 to 4,836 metres.
Hephthocara is a small genus of Indo-Pacific viviparous brotula.
Eurypleuron is a genus of pearlfishes, with these currently recognized species:
Pyramodon is a genus of pearlfishes, with these currently recognized species:
Lepophidium is a genus of cusk-eels.
Ophidion 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.
Parophidion is a genus of cusk-eels found in the Atlantic Ocean and the Mediterranean Sea.
The banded cusk-eel is a species of cusk-eel found along the southeast coast of South America from southern Brazil to northern Argentina. It occurs at depths of from 40 to 150 metres and is of minor importance in commercial fisheries. This species grows to a length of 31 centimetres (12 in) TL. It is the only known member of its genus. The generic name honours the American ichthyologist Edward C. Raney (1909-1984) of Cornell University who introduced the describer Charles R. Robins to ichthyology.
Atractodenchelys phrix, known under the common name "Arrowtooth eel" is an eel in the family Synaphobranchidae. It was described by Catherine H. Robins and Charles Richard Robins in 1970. It is a marine, deep water-dwelling eel which is known from its type locality in the eastern Caribbean, in the western central Atlantic Ocean. It is known to dwell at a depth range of 385–425 metres.
Atractodenchelys robinsorum is an eel in the family Synaphobranchidae. It was described by Emma Stanislavovna Karmovskaya in 2003. It is a marine, deep water-dwelling eel which is known from the Chesterfield Islands in the southwestern Pacific Ocean. It is known to dwell at a depth of 710 metres.
Bythitinae is a subfamily of viviparous brotulas, one of the two subfamilies in the family Bythitidae. This subfamily is characterised by having the dorsal, caudal and anal fins combined. They are mostly found in temperate to tropical seas, from reefs to the benthopelagic zone, but some species from the North Atlantic Ocean occur in into Arctic waters.
