All Caranx Species: Posterior straight part of lateral line with enlarged hardened scutes; adults of most species with pectoral fins long and falcate, distinctly longer than head length. Scales obvious over most or all of body. No black saddle on upper part of caudal peduncle; scutes on straight part of lateral line 23-56, and relatively large (maximum height at least equal to pupil diameter); body slightly to moderately compressed and ventral profile not more convex than dorsal profile. Lining of mouth not distinctly white and dark; anal-fin spines distinct and movable; no scutes in posterior part of lateral line point forward. Lobe of second dorsal fin distinctly longer than height of longest dorsal-fin spine; lips of adults not papillose. Upper jaw with several rows or a band of teeth; both caudal-fin lobes about equal in length; caudal fin with paired keels edge (FAO 2002).
Caranx latus
Unique Characters: Body dark blue to bluish grey above, silvery white to golden below. Black spot on opercle often indistinct or absent. Posterior scutes often blackish. Upper dorsal may have some black as well as a black margin on yellow caudal fin. Chest completely scaly; no oval black spot on pectoral fin. Lower gill rakers 16-21. No dark blue stripe extending along back and through lower caudal-fin lobe. Lateral-line scutes 22-39. Dorsal- and anal-fin rays 19-23 and 16-19, respectively. Adults with upper jaw extending to vertical at rear margin of eye. Dorsal-fin lobe shorter than head, about 5.6-6.0 times in fork length.
