Description
The basilisk blenny is a colourful, scaleless blenny of the family Blenniidae reaching about 18 cm. The greenish to brown body bears a few dark cross-bars, and the male has a conspicuous crest on the steep head. The species lives on shallow sand and seagrass bottoms and in brackish coastal lagoons of the Mediterranean, often in environments with varying salinity where few other fish thrive. As an omnivore it grazes algae and seeks small crustaceans, worms and molluscs. Breeding males defend a cavity or empty shell, in which they guard the clutch laid by the female until it hatches. Because of its small size it has no fishery importance, but it is typical of seagrass and lagoon environments.
