Description

Dactyloscopus tridigitatus is a sand stargazer (family Dactyloscopidae) of the western Atlantic. The species grows to about 9 cm and has an elongate body with upward-directed eyes and mouth, adapted to a life buried in the bottom. It lives in shallow, often surf-swept water down to about 29 m and burrows into soft sandy bottoms, where it waits concealed for passing prey. As an ambush predator it feeds on small bottom animals. The species is harmless to humans and of no fishery interest.
