Description

The Tanega rockskipper is a combtooth blenny (Blenniidae) from the surf zone and tide pools of the northwest Pacific. The species grows to about 8 cm and has a scaleless, stocky, brown-marbled body with a blunt head, high-set eyes and small cirri. With comb-like teeth it rasps algae from rocks; at low tide it nimbly skips from pool to pool and can stay briefly out of the water. The fish is harmless to humans.
