Short description

Dorsal spines (total): 6; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 7 - 9. Body with dark bars crossing lateral line, each bar oblique in upper half, but nearly vertical in lower half; caudal fin largely yellowish.

Found near prominent current-swept lagoon or seaward reefs (Ref. 9710); also in bays, estuaries and turbid inner lagoons (Ref. 9768). Diurnal and solitary, although the young form schools. Feeds mainly on fishes but also takes squid. Sold fresh, frozen or dried salted. Reports of ciguatera poisoning need confirmation.

IUCN Red List Status (Ref. 115185)

Not Evaluated
