Description

Stampfli's flounder is a small, left-eyed flatfish of the family Paralichthyidae reaching about 18 cm. Both eyes lie on the left side, which is sandy-brown with dark spots; the underside is white. The species lives on sand bottoms of shallow coastal water, lagoons and estuaries along the West African coast and tolerates strongly varying salinity. By day it presses against the bottom or partly buries itself; on the bottom it hunts small crustaceans and worms. Like all flatfish the young start symmetrical and, after metamorphosis, sink onto their side to the bottom. Because of its small size it has little commercial importance, though it comes up as bycatch.
