Biology     Glossary (e.g. epibenthic)

Adults are found in coastal waters near corals and rocks, also in shallow lagoons (Ref. 30573). Solitary species on inshore reefs (Ref. 48635). Small groups frequently patrol perimeter of reefs (Ref. 90102). Juveniles may enter estuaries (Ref. 5213). Behaviour of shadowing a larger fish was observed, expected to be more common for juvenies (B. Hazes, pers. comm. 3/2023).
