More Info


Distribution

Endemic to western and northern Australia from the Houtman Abrolhos islands, Western Australia, to the Arafura Sea, Northern Australia. The species is common in the Shark Bay region of Western Australia.

Inhabits inner reefs with large boulders and open areas with algal-covered rocks, sponges and other attached invertebrates at depths of 1.5–150 m.

Feeding

Feeds mostly on hard-shelled invertebrates such as crustaceans, molluscs, crabs and sea urchins.

Fisheries

Taken by commercial and recreational fishers in the north-western regions (Gascoyne and Pilbara/Kimberley) of Western Australia. The flesh is of a high quality and is sold either as fillets or whole fish.
Current regulations place a minimum size limit for tuskfish species of 40 cm in Western Australia. This essentially protects the Bluespotted Tuskfish from capture, as the species rarely reaches that length.

Etymology

The specific name cauteroma is from the Latin cauteroma meaning “brand” in reference to the characteristic brand-like marking dorsally on the side of the body.
