Description

The sand stargazer is a sand stargazer (Dactyloscopidae) from the eastern Pacific. The species is small and has upward-directed eyes and mouth, so that half-buried in the sand it can peer upward. It lives bottom-bound on sand bottoms of shallow coastal waters. As an ambush hunter it darts up at passing small fishes and invertebrates. Unlike the true stargazers it is not venomous. The species is harmless to humans.
