Description

The fivebeard rockling is a small cod relative of the family Lotidae reaching about 25 cm. The elongate, yellow-brown body bears five barbels: four around the snout and one on the chin. The first dorsal fin is peculiar: it consists of a row of fine, constantly vibrating rays in a groove, followed by a long second dorsal fin. The species lives on sand and mud bottoms in shallow coastal water and tidal areas of the north-eastern Atlantic, the North Sea and the Baltic, often among stones and weeds. Mainly at night it hunts small crustaceans, worms and small fish. Because of its small size it is not fished, but it is a common inhabitant of the tidal zone.
