Western Pacific: Ryukyu Islands to New Caledonia and the Great Barrier Reef, including New Guinea, Sulawesi (Celebes), Admiralty Islands, Palau, and Philippines. Recently recorded from Tonga (Ref. 53797). Also known from eastern Indian Ocean from Rowley Shoals and off Broome, Western Australia.
Adults occur over sand bottoms in the vicinity of coral reefs. Usually seen singly. They feed on fishes and sand-dwelling crustaceans and mollusks. Mature individuals aggregate to spawn along seaward reefs (Ref. 9710). They are occasionally seen in markets.
