Description

The narrownecked oceanic eel is a deep-sea eel (family Derichthyidae) occurring worldwide in the open ocean. The species reaches about 40 cm and has a slender, snake-like body with a markedly narrow neck behind the head. It lives meso- to bathypelagically in the deep water column and feeds on small fishes and crustaceans. The eggs and the leaf-shaped larvae (leptocephali) are planktonic and drift with the current. Because of its deep-sea habits the species is little studied. It is harmless to humans and of no fishery value.
