Description

The weed blenny is a blenny (Blenniidae). The species has an elongate, scaleless body with a blunt head and crest-like skin flaps above the eyes. Adults inhabit shallow, weed-covered rocky reefs, including tide pools, where their colour provides camouflage. They feed on small benthic invertebrates and algae. They are demersal spawners: the adhesive eggs attach to the substrate and are guarded by the male. Owing to scarce data the species is regarded as data deficient. It is harmless to humans.
