Biology     Glossary (e.g. epibenthic)

Found in protected coastal reef in mixed algae and coral habitat (Ref. 48635). Common on inshore coastal reefs but absent in clear offshore reefs (Ref. 9710). Juveniles have a demersal existence in shallow water in reef habitats, especially around coral rubble (Ref. 27259). Migrate over short distances to spawn, forming aggregations (Ref. 6390). May move into shallow water to feed (Ref. 6390). Eggs float just below the water surface (Ref. 6390). Pelagic larvae are found in habitats similar to those of the adults (Ref. 27260). Juveniles feed on small fish and invertebrates such as crustaceans and squid (Ref. 27261). Commonly used for food. Its flesh is delicate and well appreciated (Ref. 5503). Solitary (Ref 90102).
