Description

The walleye surfperch is a surfperch (Embiotocidae) from the eastern Pacific off the west coast of North America. The species grows to about 30 cm and has a deep, strongly silvery body with large eyes, to which the English name refers, and black margins on the pelvic fins. It lives in the surf of sandy beaches and over sand near rocks, often around piers, frequently in dense schools. It feeds on small crustaceans. Like all surfperches it is viviparous: the female carries the developing young and bears live young. The species is harmless to humans.
