Description

The dusky flounder is a left-eyed flatfish of the family Paralichthyidae (sand flounders) reaching about 30 cm. Both eyes lie on the left side of the head; in adult males the eyes are set wider apart than in females. The brown, marbled upper side gives good camouflage on sand and mud bottoms, where the fish lies half-buried watching for prey. The species lives over soft bottoms of the continental shelf along the western Atlantic coast from the USA to Brazil. On the bottom it ambushes small crustaceans, worms and small fish. With its tasty flesh it is landed as bycatch and traded locally.
