Description

The giant sand stargazer is a bottom fish of the sand stargazer family (Dactyloscopidae) from the eastern Pacific. The species grows to about 15 cm and has an elongate body with upward-directed eyes and an obliquely upturned mouth, adaptations to a buried way of life. It inhabits sand bottoms of protected beaches and near-shore sites in less than five metres of water, where it buries itself almost completely and leaves only the eyes exposed to lie in wait. As an ambush predator it seizes passing small invertebrates and small fishes. The species is harmless to humans.
