Western Pacific: Ryukyu Islands to the Indo-Australian Archipelago (Malay Peninsula to New Guinea and northern Australia).
Adults inhabit coral reefs, from shallow water to depths of at least 50 m. They occur singly. They feed mainly on fishes. Frequently ciguatoxic in certain areas. Sold in Hong Kong live fish markets (Ref. 27253). It causes ciguatera poisoning in some areas. Banned for sale in Australia. (Ref. 90102)
