Biologie     Glossaire (ex. epibenthic)

Inhabits seagrass beds and sandy areas of lagoons and outer reef slopes. Found singly or in schools. Feeds mainly on crustaceans, mollusks, and fish. Marketed fresh (Ref. 9775).

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

Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes (Ref. 103751). Juvenile hermaphroditism is exhibited by this species (Ref. 35994).
