Bunbury and offshore reefs of Western Australia, Ashmore Reef, Timor Sea, and around the tropical north to Bermagui, New South Wales; also Christmas Island and Cocos (Keeling) Islands in the eastern Indian Ocean, and Norfolk Island in the Tasman Sea. Elsewhere, the species is widespread in the tropical Indo-West Pacific, from the Red Sea and East Africa east to the Solomon Islands, north to southern Japan, south to Australia, New Caledonia and northern New Zealand.
Large adults inhabit protected reefs in sheltered bays and deeper offshore reefs to 70 m, occasionally forming large schools. Small juveniles resemble leaves and shelter amongst floating debris. Larger juveniles may form schools beneath Sargassum rafts.

Features

Dorsal fin V-VI, 28-37, spines hidden in front margin of fin; Anal fin III, 22-28; Pectoral fin 16-18. 

Body deep, strongly compressed, head profile almost vertical, large adults (> 35 cm SL) with bony hump from top of head to interorbital region; five pores on lower jaw. Jaws with bands of slender, flattened, tricuspid teeth, the middle cusp slightly longer than lateral cusps; vomer with a few teeth, palatine teeth absent.

Colour

Yellowish silvery or dusky, with a black (or dusky) bar through eye and another dark bar from dorsal-fin origin across rear edge of operculum and pectoral-fin base to belly, where it usually encloses a black blotch, with another smaller black vertical streak often present at origin of anal fin. Median fins dusky yellow, with black margins posteriorly. Pelvic fins yellow, dusky yellow or blackish.
