Description

The redlip blenny is a reef-dwelling blenny of the family Blenniidae reaching about 19 cm. The scaleless, brownish body has a blunt head with thick lips, fringed tentacles above the eyes and a row of fine, comb-like teeth with which the fish scrapes algae from the rocks. The species lives on shallow tropical and subtropical reefs in the Atlantic, including the eastern island groups and the western Atlantic coast. It is active by day and strongly territorial: the male fiercely defends a hole and guards the eggs laid there. As an algae grazer the species helps keep reef growth short.
