Short description

Dorsal spines (total): 7; Dorsal soft rays (total): 25-30; Anal spines: 2; Anal soft rays: 18 - 22.

Adults are found in oceanic and coastal waters, generally near the surface over reefs or sometimes far from the coast often around floating logs or other debris (Ref. 9283, 11230, 48635, 90102). May form large schools (Ref. 9283, 48635). They feed on invertebrates, mainly on larger crustaceans of the zooplankton, and small fishes (Ref. 9283, 26145). Eggs are pelagic (Ref. 4233). Good food fish (Ref. 9626) and a valued game fish (Ref. 26938); marketed fresh and salted or dried (Ref. 9283); also frozen and used for sashimi (Ref. 9987).

IUCN Red List Status (Ref. 115185)
