Description

Oligoplites saliens, the castin leatherjacket, is a slender, strongly laterally compressed jack of the family Carangidae from coastal waters of eastern South America. The species has a silvery body with a leathery skin and separate finlets behind the dorsal and anal fins, and reaches about 50 cm. Adults live over soft bottoms of the continental shelf, often inshore and in estuaries, but also pelagically throughout the water column. They can filter plankton from the water by swimming with an open mouth. Juveniles feed mainly on planktonic crustaceans. The species is of local fishery importance.
