Description

The notchtail stargazer is a sand stargazer (Dactyloscopidae) from the eastern Pacific. The species has an elongate body with upward-pointing eyes and an upturned mouth, adapted to life largely buried in sand. From its hiding place only the eyes and mouth project above the sediment, with which as an ambush hunter it springs on passing prey. It lives on shallow sandy bottoms of coastal waters and feeds on small crustaceans and small fishes. The species is harmless to humans.
