Description

The crested blenny is a small blenny of the family Blenniidae from the western Atlantic off the east coast of North America. The species grows to about 10 cm and has a scaleless, brownish and mottled body with small skin flaps above the eyes. It inhabits shallow, hard substrates such as rocks, oyster beds and piers in coastal and estuarine water. As a small bottom dweller it feeds on small invertebrates and algae. The eggs are adhesive and attached to the substrate by a pad and guarded by the male. Owing to its camouflage and secretive habits it is little noticed. It is harmless to humans.
