Description

The fish doctor is an eel-like Arctic fish of the family Zoarcidae (eelpouts) reaching about 56 cm. The elongate, scaleless body is greenish to brown tinged and has a continuous fin fringe in which the dorsal, tail and anal fins merge; clear pelvic fins are absent. The species lives on sand and mud bottoms of the Arctic Ocean and the adjacent cold Atlantic, from shallow to moderate depths, often among stones and in cavities. As a bottom-dweller it hunts small crustaceans, worms and molluscs. The female lays a clump of fairly large eggs and guards them. Because of its far-northern range it is little known here and has no fishery importance.
