Description

The tentacled blenny is a small, scaleless blenny of the family Blenniidae reaching about 15 cm. Characteristic is a conspicuously long, branched skin flap (tentacle) above each eye; the brownish body bears six to seven faint dark cross-bars. Unlike many blennies, which live on rocks, this species often stays on sand and stone bottoms in shallow water, in the Mediterranean, the Black Sea and the adjacent eastern Atlantic. As a bottom-dweller it grazes on algae and small invertebrates. The male defends a shelter and guards the eggs laid in an empty shell or cavity until they hatch. Because of its small size it has no fishery importance.
