Indo-Pacific: East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to Australia and the Austral Islands; throughout Micronesia.
Occurs along exposed reef margins and outer reef slopes. Has been observed at depth of 183 m in Hawaii (Ref. 1602). Benthopelagic (Ref. 58302). Secretive during the day and hides in holes and crevices of surge channels. Feeds at night on crustaceans, crustacean larvae, polychaete worms, and small fishes. Spine of preopercle venomous.
