Description
The coral blenny is a small blenny (Blenniidae) from the western Pacific. The species reaches only about 6 cm and has a brown, mottled body that blends well against rock and coral. Adults occur singly or in small groups on boulder habitats, where they 'perch' on rock and living coral, on shallow coastal reefs. The species is common on coastal and inner reef crests with rich coral growth. With its comb-like teeth it grazes algae and detritus from the substrate. The adhesive eggs are laid on the bottom and guarded.
