Description

The freckled blenny is a small bottom fish of the combtooth blenny family (Blenniidae) from the western Atlantic and Gulf of Mexico. The species grows to about 10 cm and has a stocky, scaleless body with fine freckles and fringes (cirri) above the eyes. It inhabits shallow coastal waters, oyster beds, pilings and hard structures, where it shelters in cavities and empty shells. With short, chisel-like teeth it scrapes algae and film from the substrate; it is predominantly herbivorous. The male guards the eggs laid in a cavity. Owing to its small size the species is harmless to humans.
