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

Eastern Indian Ocean: endemic to Australian waters. Distributed from the Recherche Archipelago off Esperance, to Beagle Island, although they are rare north of Shark Bay. Records from Japan (Ref. 559, 12517) and Taiwan (Ref. 5193) are Glaucosoma buergeri (Ref. 27621).

Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 9. One dark vertical band through eye which may disappear with an increase in size; 11 dorsal fin rays and 9 anal fin rays. Supraclavicle not developed into a bony shield. Peritoneum and gill rakers pale; lateral line with 44 to 48 pored scales; juveniles with wide dark horizontal bands wider than interspaces.

Biology     Glossary (e.g. epibenthic)

Westralian jewfish live in shallow inshore waters and depths to over 200 m (Ref. 27560). They are present over hard, flat sea beds (e.g. limestone shelf) and in reefs, wrecks and underwater caverns and gutters. Adult fish move into shallower waters in the cooler months between April and June (Ref. 27560, 27561). Juveniles tend to remain in shallower water than adults and are rarely found in waters more than 100 m deep (Ref. 27560). Adults feed mainly on fish, also rock lobsters, crabs, squid, octopus and cuttlefish. Marketed as fresh fish (Ref. 10384).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Female Westralian jewfish are broadcast spawners, releasing floating eggs into the water column; these are pelagic and can be carried large distances on ocean surface currents (Ref. 6390). Larvae feed on plankton (Ref. 6390).
