Description
The bar jack is a fast reef predator of the family Carangidae reaching about 70 cm. The streamlined, silvery-grey body bears a conspicuous dark-blue band that runs from the second dorsal fin obliquely along the back into the lower tail lobe, giving the species its name. The species lives over reefs and in clear coastal water of the western Atlantic and the Caribbean. In fast schools it hunts small fish, shrimps and crustaceans, often alongside other hunting predators or rays. It is a popular sport and food fish, though in some areas the flesh can carry ciguatera. Because of its speed it is a favoured opponent on the rod.
