Description

The moonstruck sand stargazer is a small sand stargazer (Dactyloscopidae) from the eastern Pacific. The species has an elongate body with an upward-directed mouth and eyes high on the head, adapted to life buried in sand. It lives on sand bottoms of shallow coastal waters, where it buries up to just below the eyes and lies in wait. As an ambush hunter it springs on passing small crustaceans and small fishes. The species is harmless to humans.
