Description

The sand seatrout is a slender, silvery drum of the family Sciaenidae reaching about 64 cm. The streamlined body is silvery with a yellowish cast; the upper jaw holds a pair of large, pointed canine teeth. Like many drums it makes drumming sounds with muscles around the swim bladder. The species lives in schools on sand and mud bottoms of shallow coastal water and estuaries of the Gulf of Mexico and tolerates brackish water. On the bottom it hunts shrimp, small fish and other crustaceans. Because of its tasty flesh and good fight it is a prized sport and market fish along the Gulf coast and an important coastal species.
