of the genus. Carangid classification was initially very difficult, with many genera and species described, many of which were synonymous. 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 ''carangue'', meaning 'fish of the Caribbean'.

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 , but with 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
