Indo-Pacific: East Africa south to Durban, South Africa (Ref. 4420) and east through Indonesia to Samoa, north to southern Japan and south to New Caledonia.
Lives in clear coastal to outer reef habitats (Ref. 48637). Occurs in clear seaward reefs adjacent to steep drop-offs. A solitary species (Ref. 9710). Uncommon to rare throughout most of its range (Ref. 9770). Adults usually seen along deep drop-offs, swimming about openly and may retreat to caves when approached. Juveniles secretive in small caves with rich invertebrate growth (Ref. 48637). Diet consists of sea urchins, crabs and other crustaceans, mollusks, and tunicates (Ref. 9770). Marketed fresh (Ref. 9770). Among the most highly prized aquarium fishes (Ref. 1602).
