Description
The lesser African threadfin is a silvery bottom fish of the family Polynemidae (threadfins) reaching about 50 cm. Characteristic of the family is the blunt, projecting snout with an inferior mouth, and a row of separate, thread-like lower pectoral-fin rays that feel over the muddy bottom for prey like sensitive feelers. The species lives in schools over sand and mud bottoms of turbid coastal water and estuaries along the West African coast and tolerates brackish water. With its feeler rays it detects shrimps, small crustaceans, worms and small fish. The threadfin is an important commercial fish in West Africa, heavily landed by coastal and estuarine fisheries.
