More Info


Distribution

Shark Bay region and offshore reefs of north Western Australia, around the tropical north to Batemans Bay, New South Wales on the southeast coast; also Norfolk Island in the Tasman Sea. Elsewhere, the species is widespread in the tropical Indo-west-central Pacific.

Inhabits shallow coastal waters around coral and rocky reefs, feeding mostly on molluscs. Juveniles usually school in shallow sandy and muddy areas, often around river mouths, and along sandy shores.

Feeding

Carnivore - feeds on hard-shelled invertebrates, especially molluscs such as oysters.

Fisheries

Of minor commercial importance, particularly in artisanal fisheries, and aquacultured in some areas. Also a popular sports fish and displayed in public aquaria.

Etymology

The species is presumably named for the physician-naturalist Marcus Elieser Bloch, a leading ichthyologists in the 18th century.
