Short description

Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 11-13; Anal spines: 0; Anal soft rays: 11 - 15; Vertebrae: 39. Anterior spines of first dorsal fin much higher than the those mid-way, giving the fin a strongly concave outline. Interpelvic process small and bifid. Body naked except for corselet and lateral line. Swim bladder absent. Incipient protuberances on 33rd and 34th vertebrae. Back with broken oblique stripes (Ref. 168). Caudal peduncle with 7-8 finlets. Dark stripes on the back and with 3-7 dark spots between pelvic and pectoral fins (Ref. 35388).

Found in neritic waters close inshore (Ref. 13628). This schooling species is an opportunistic predator which feeds on virtually everything within its range, i.e. crustaceans, fishes (mainly clupeoid), squids, heteropods and tunicates. Eggs and larvae are pelagic (Ref. 6769). Specialized traps (madragues) are used in Tunisia and Morocco. Diving bird flocks may indicate large schools (Ref. 9710). Utilized fresh, dried-salted, smoked, canned and frozen (Ref. 9987). A popular game fish (Ref. 9710).

IUCN Red List Status (Ref. 115185)

Least Concern (LC)

Threat to humans

Reports of ciguatera poisoning (Ref. 30303)
