Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Western Pacific: known only from the northern coasts of Australia, south to Shark Bay in western Australia, along the east coast of Queensland south to northern New South Wales. Recently reported from the Gulf of Papua (Ref. 9684) and Ouvéa Atoll, Loyalty Islands (Ref. 13236).

Biology     Glossary (e.g. epibenthic)

Form schools near individual bays and reefs in Barrier Reef waters. With the rising tide, they move into shallow water over the reef flats, feeding on schools of clupeoid fishes that concentrate there. Utilized as a food fish.
