Description

The eelpout is an eel-like coastal fish of the family Zoarcidae reaching about 52 cm. The elongate, brown-yellow and spotted body has a continuous fin fringe in which the dorsal, tail and anal fins merge, and thick lips. The species lives on sand and mud bottoms in shallow coastal waters and tidal areas of the north-eastern Atlantic, the North Sea and the Baltic, often among stones and weeds. It hunts small crustaceans, worms, shellfish and fish eggs. Very unusual for a bony fish, the eelpout bears live young: after internal fertilisation the female carries the embryos and in winter gives birth to a few dozen fully formed young. For this it owes its Dutch nickname 'eel mother'.
