Description

The longfin sanddab is a left-eyed flatfish of the family Paralichthyidae from the eastern Pacific, from California to Costa Rica. The species reaches about 25 cm; both eyes lie on the left side and the eyed side is brown with fine, dark speckling that provides camouflage. A few anterior fin rays are elongated, to which the name refers. It inhabits sand and sandy-mud bottoms of the continental shelf to about 200 m deep, where it lies half-buried in ambush for small bottom invertebrates and fishes. The species is used fresh as a panfish.
