Eelpout

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.

Eelpout
Gymnelus hemifasciatus
Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Class:	Actinopterygii
Order:	Perciformes
Family:	Zoarcidae Swainson, 1839[1]
Subfamilies
Gymnelinae Gill, 1863 Lycodinae Gill, 1861 Lycozoarcinae Andriashev, 1939 Zoarcinae Swainson, 1839

They are conventionally placed in the "perciform" assemblage; in fact, the Zoarcoidei seem to be specialized members of the Gasterosteiformes-Scorpaeniformes group of Acanthopterygii.[2]

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.

Genera

This family contains about 61 genera and 300 species:

Bothrocara brunneum

Lycodes turneri

Pachycara sp.

Zoarces viviparus
