Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic. Tropical
Eastern Atlantic: African coast from Mauritania south at least to Moçamedes (southern Angola)(Ref. 58464). Confirmed historical records from Ascension Island and the Mediterranean Sea (Ref. 58464, 81654).

Maturity: Lm ?  range ? - ? cm
Max length : 53.0 cm FL male/unsexed; (Ref. 58464)
soft rays: 17 - 19;
Vertebrae: 24. Diagnosis: member of the Caranx hippos complex, characterized by the following: segmented dorsal-fin rays 21-23 (exceptional 24); segmented anal-fin rays 17-19, usually 18; posttemporal bones hyperossified in specimens larger than 20 cm FL; cleithrum, first pterygiophore of dorsal and anal fins, and neural spines of vertebrae relatively slender and never hyperossified; for individuals > 20 cm FL, heights of longest dorsal- and anal-fin rays both 0.7-1.3 in HL; in adults, anal-fin lobe white anteriorly and remainder of fin gray to brown (Ref. 58464). Black spot on pectoral fin; median pre-pelvic patch of scales, rest of chest naked; well-developed adipose eyelid at posterior eye border; upper jaw reaches to about level of posterior eye border in adults; dorsal soft fin ray lobe longer than head in large adults; 25-40 scutes on the posterior part of lateral line (Ref. 81654).
Coloration: ground colour greenish to bluish, black-bluish dorsally, white-silvery to yellowish or golden ventrally; opercle with a distinct black spot; pectoral fin with a characteristic black blotch in adults; distal part of soft dorsal fin lobe dark to pale; adults with anal fin lobe mostly white (vs anal fin lobe entirely yellow in C. hippos); juveniles with 5 dark bars on body (Ref. 81654).
Attains at least 80 cm fork length (Ref. 81654).
