Description

The northern rockling is a small cod relative of the family Lotidae reaching about 20 cm. Around the mouth it carries five barbels — two pairs on the snout and one on the chin — with which it searches the bottom by touch; this distinguishes it from rocklings with three barbels. The first dorsal fin consists of a low row of fine, thread-like rays in a groove, the second is long and low. The brownish body blends well among weeds and stones. The species lives on rocky and stony bottoms of shallow coastal water of the north-eastern Atlantic and the North Sea, often in tide pools. Mainly at night it hunts small crustaceans, worms and small fish. Because of its small size it has no fishery importance.
