Description

The shortjaw mudsucker is a goby (Gobiidae) from the eastern Pacific. The species is small and has a stocky body with, as is typical of gobies, pelvic fins fused into a sucker. It inhabits high intertidal pools and tidal rivulets of rocky and sandy shores and can tolerate oxygen-poor conditions. As a bottom hunter it snaps small crustaceans, worms and detritus. Owing to its limited range it is considered vulnerable. The species is harmless to humans.
