Summary:
A greenish to bronze drummer becoming pale greyish to silvery below, with faint golden horizontal lines along the body, often a white or silvery streak on the cheek beneath the eye, and often a narrow thin pale stripe below the dorsal fin base. Bright yellow individuals are occasionally seen, often with blotches or patches of black and paler yellow or whitish areas. Juveniles are grey with white or pale spots on the body and fins.

Prior to 2012, the Pacific Drummer was known in Australia as Kyphosus pacificus, now considered to be a junior synonym of K. sectatrix (Knudsen & Clements 2013). The species has also been called Kyphosus bigibbus.

Distribution

Heron Island, Queensland, to Ulladulla, New South Wales, also the Lord Howe Island region, and Norfolk Island in the Tasman Sea. Elsewhere, the species is widespread and locally abundant in subtropical waters: in the Pacific, Atlantic and Indian Oceans, the Red Sea and the Mediterranean Sea.

Forms schools (often with other drummer species) on shallow reefs, often in the surge zone. Also occurs over algal reefs and seagrass beds, sandy and rocky bottoms, and reef flats. Juveniles, which often shelter among floating Sargassum seaweeds, can disperse across vast distances.

Features

Dorsal fin X-XI, 11-12; Anal fin II-III, 10-12. Gill rakers on external side of lower limb on first arch 14–18, and on upper limb 5–8; Lateral line with 63–76 scale rows in total, of which 51–61 has pores; Longitudinal scale row 60–69 scales; Precaudal and caudal vertebrae 10 and 15, respectively; Dorsal and anal pterygiophores 20–21 and 12, respectively. 
Anal fin relatively highly elevated, with second anal-fin ray longest 8.5–15.2 %SL. Pectoral fin length 13.3–24.1 %SL. Jaws with a regular row of close-set, strong, incisor-like, round-tipped teeth of a peculiar hockey stick-shape, their bases set horizontally, resembling a radially striated bony plate inside mouth.

Feeding

Omnivore - feeds on benthic algae, as well as on small crabs and molluscs.
