Description
The peacock blenny is a colourful, scaleless blenny of the family Blenniidae reaching about 14 cm. The greenish body bears narrow, blue-green cross-bars; adult males have a striking high crest on the head and an eyespot-like, blue-rimmed marking at the front of the dorsal fin, while females are more subdued. The species lives on shallow rock and stone bottoms of the Mediterranean, the Black Sea and the adjacent eastern Atlantic, often in brackish lagoons and estuaries where few other fish thrive. As an omnivore it grazes algae and seeks small crustaceans, worms and molluscs. The male defends a cavity or empty shell and guards the clutch laid in it.
