The eelpouts are the ray-finned fish family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance, with elongated bodies and the dorsal and anal fins continuous with the caudal fin. All of the roughly 300 species are marine and mostly bottom-dwelling, some at great depths. They are conventionally placed in the "perciform" assemblage in fact, the Zoarcoidei seem to be specialized members of the Gasterosteiformes-Scorpaeniformes group of Acanthopterygii. The largest member of the family is Zoarces americanus, which may reach 1.1 m in length. Other notable family members include Lycodapus and Gymnelus.
