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).
在沿岸区域, 深的舄湖与近的珊瑚礁中栖息于砂质底部。 (参考文献 30573) 稚鱼与小的成鱼通常形成松散的鱼群海草床，红树林沼泽与水浅的沙地区域之上虽然成鱼通常独居在较深的水域。 主要吃甲壳动物与软件动物，但是棘皮动物, 多毛类动物与鱼也在相当多的量被消费。 (参考文献 2295) 一个雌性先熟的雌雄同体.(参考文献 55367)
