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.
