More Info


Recorded from Cape Freycinet, southern Western Australia, to Sydney, New South Wales, and Lord Howe and Norfolk islands, in the Tasman Sea. Found elsewhere in the tropical western Pacific.

Inhabits coral reefs, usually feeding in small schools over sandy and rubble areas between bommies and along reef edges during the day. At night, they move out onto open sandy areas to forage. 



Carnivore - feeds on crustaceans, echinoderms, molluscs and fishes - preferring crabs and sea urchins.
