Description

The black jack is a dark, powerful jack of the family Carangidae reaching about 1 metre. The laterally compressed body is grey-black to almost black, with a steep, high head profile and a row of stout bony scutes along the tail base, characteristic of the family. The species lives pelagically near deeper and remote reef, islands and steep slopes in tropical seas worldwide. In loose groups it hunts fish, crustaceans and squid. It is a prized, hard-fighting sport fish, although in some areas its flesh can carry ciguatera (a natural fish toxin), which calls for caution when eating it.
