ous. Later reviews of the family eventually placed 21 species into Carangoides, leaving a number of genera synonymous with it. Carangoides takes priority over these other genera because its type species, Caranx praeustus, was described by an unknown author before the other species and genera were erected. The species of the genus are often referred to as jacks or trevallies, and sometimes more specifically as 'island jacks'. The name Carangoides is derived from the French

Description

In their general morphology, the species of Carangoides are very similar to a number of other carangid genera, especially Caranx. They grow to a range of sizes, most attaining a length less than 50 cm, although the largest fish of the genus reaching at least 1 m and over 65 kg in weight. They have a relatively deep, compressed body, with the dorsal profile usually far more convex than the ventral, with a tapering posterior. The dorsal fin

 is in two parts, the first consisting of spines, and the second of one or two spines followed by a number of soft rays. The anal fin has detached spines preceding a long soft ray section headed by up to two spines. The caudal fin is large and forked and the pectoral fin is large, usually longer than the head. All species have scutes on the posterior section of their lateral line
