Description

The bay whiff is a small, oval flatfish of the family Paralichthyidae reaching about 21 cm. Like all flatfish the larva starts symmetrical and tilts onto the bottom as it grows; in this species both eyes lie on the left side. The upper side is brown with dark spots and matches the colour of the bottom, the underside white. The species lives buried on soft sand and mud bottoms of coastal water, estuaries and lagoons along the western Atlantic coast; juveniles range far into brackish water. As an ambush hunter it takes small crustaceans, worms and small fish. Because of its small size it is mainly a prey fish and bycatch, not targeted by fisheries.
