Description

The Mediterranean bigeye rockling is a small cod relative of the family Lotidae reaching about 40 cm. Like other rocklings it carries three barbels — two on the snout and one on the chin — with which it searches the bottom by touch; its large eyes are conspicuous. The first dorsal fin consists of a row of fine, thread-like rays, the second is long and low. The red-brown body blends well against rocks. The species lives hidden on rocky and gravel-covered bottoms of the Mediterranean and the adjacent eastern Atlantic, from shallow to moderate depths. Mainly at night it hunts small crustaceans, worms and small fish. Because of its small size and hidden lifestyle it has no fishery importance.
