Description

Norman's blenny is a small, scaleless blenny of the family Blenniidae (combtooth blennies) reaching about 11 cm. The brownish body with faint vertical bars has a blunt, high little head, often with small skin flaps (tentacles) above the eyes. Like other blennies the species has no scales but a slimy skin and usually sits on the bottom, resting on its pectoral fins. It lives among rocks, holes and growth of shallow coastal water along the West African coast, where it defends a territory. It grazes algae and picks small crustaceans and growth from the bottom. The male guards the eggs in a crevice or empty shell. Because of its small size it has no fishery value.
