Description

The Whitesaddle stargazer is a sand stargazer (Dactyloscopidae) from shallow, clear sandy water of the eastern Pacific. The species grows to about 8 cm and has a slender, sandy body with eyes set high on the head and an upward-slanted mouth. As a bottom-dweller it buries almost entirely in loose sand, with only the eyes showing, and snaps from that ambush at small crustaceans and small fish. The fish is harmless to humans.
