Colour of body greenish or grey, shading to white below, centers of scales on upper sides often white; posterior margin of opercle and sometimes base of pectoral fins red; pectoral fins white, yellow, or pinkish; pelvic and anal fins white to orange; dorsal fin white and orange mottled with a reddish margin; caudal fin mottled orange or reddish (Ref. 114226).

Biología     Glosario (por ej. epibenthic)

Inhabits sandy bottoms in coastal areas, deep lagoons and near coral reefs (Ref. 30573). Juveniles and small adults commonly in loose aggregations over seagrass beds, mangrove swamps and shallow sandy areas while adults are generally solitary in deeper waters. Feeds primarily on crustaceans and mollusks but echinoderms, polychaetes and fishes are also consumed in considerable quantities (Ref. 2295). A protogynous hermaphrodite (Ref. 55367). Caught primarily by handline, traps, trawls, beach seines, and gill nets. Marketed mostly fresh (Ref. 68703).
