Westralian jewfish (Glaucosoma hebraicum)

The Westralian jewfish (Glaucosoma hebraicum) is a marine fish of the family Glaucosomatidae.

Biology

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