Etymology: Caranx: French, carangue, the name of a Caribbean fish; 1836 (Ref. 45335).
More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; oceanodromous (Ref. 51243); depth range 1 - 350 m (Ref. 7097), usually 1 - 200 m (Ref. 55173). Subtropical; 45°N - 35°S, 98°W - 14°E
Eastern Atlantic: Portugal to Angola, including the western Mediterranean. Western Atlantic: Nova Scotia, Canada and northern Gulf of Mexico to Uruguay (Ref. 7251), including the Greater Antilles (Ref. 9626). Absent from eastern Lesser Antilles (Ref. 26938). Indian Ocean records are probably misidentifications of Caranx ignobilis. Reports from Pacific refer to Caranx caninus, which may be conspecific.
Length at first maturity / Size / Weight / Age
Maturity: Lm 66.0  range ? - ? cm
Max length : 124 cm TL male/unsexed; (Ref. 5217); common length : 75.0 cm TL male/unsexed; (Ref. 2683); max. published weight: 32.0 kg (Ref. 27584)
soft rays: 15 - 18. Diagnosis: Scutes on lateral line 23 (Ref. 57392) to 42 (Ref. 13442). No scales on chest (Ref. 13442), except a small mid-ventral patch in front of pelvic fins (Ref. 13442, 57392). Upper profile of head steep (Ref. 13442). Maxilla ending approximately below (Ref. 13442, 57392) or beyond (Ref. 57392) posterior edge of eye (in adult). Front of soft dorsal and anal fins elevated; olivaceous to bluish green dorsally, silvery to brassy on the sides; prominent black spot posteriorly on gill cover at level of eye, another at upper axil of pectoral fins, and often a third on lower pectoral rays; caudal yellowish (Ref. 13442).
Generally in neritic waters over the continental shelf (Ref. 5217), from the coastline, where it is common on shallow flats, to offshore waters (Ref. 57392). Adults ascend rivers (Ref. 26938). Juveniles abundant in brackish estuaries with muddy bottoms, near sandy beaches and on seagrass beds (Ref. 5217), entering lagoons and lower courses of rivers (Ref. 57392). They form fast-moving schools, although larger fish may be solitary. They feed on smaller fish, shrimp, and other invertebrates (Ref. 5521). Often grunts or croaks are heard when caught. Eggs are pelagic (Ref. 4233).
