Biologie     Glossaire (ex. 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).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

A monandric species (Ref. 55367). Length at sex change = 30.8 cm TL (Ref. 55367). Also Ref. 103751.
