Description

The ringneck blenny is a small, scaleless rock fish of the family Blenniidae reaching about 13 cm. Above each eye the fish bears a small feathery skin flap; the colour is strikingly variable, occurring in dark, yellow and striped forms, sometimes with a dark band across the neck. The species lives on shallow rocky shores of the eastern Atlantic and the Mediterranean, and is also found in other warm seas. As a bottom-dweller it grazes on algae and small invertebrates among the stones. The male defends a territory and guards the eggs laid in a cavity or crevice until they hatch. Because of its small size it has no fishery importance, but it is a common sight on rocky shores.
