Etymology: Zebrasoma: Derived from Zebra = African horse + Greek, soma = body; referring to the stripes (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 45 m (Ref. 90102), usually 2 - 30 m (Ref. 27115). Tropical; 24°C - 28°C (Ref. 27115); 36°N - 25°S, 33°E - 134°W
Eastern Indian Ocean to the Pacific Ocean: Christmas Island and most of the East Indian region to South China Sea, Hawaii and Pitcairn Islands; north to Japan and Ogasawara Islands; south to western and eastern Australia; Replaced by Zebrasoma desjardinii in the Indian Ocean.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm SL male/unsexed; (Ref. 9710)
(total): 4 - 5;
soft rays: 23 - 26. Smalls juveniles have alternating yellow and black bars. No brush-like patch of setae posteriorly on side of body. Dorsal fin very elevated, the longest ray 2.1 to 2.5 times in SL (Ref 9808).
Benthopelagic (Ref. 58302). Occurs in lagoon and seaward reefs from the lower surge zone to a depth of at least 30 m. Solitary juveniles found among rocks or coral (Ref. 58534) of shallow protected, sometimes turbid reefs (Ref. 1602, 48637). Feeds on leafy macroalgae. It possesses, fewer and larger pharyngeal teeth, compared to the other Zebrasoma spp. (Ref. 33204). Diurnal species (Ref. 113699:32); courtship and spawning takes place from morning to afternoon and is often confined to ebb tides (Ref. 38697). The species is never poisonous (Ref. 4795). Minimum depth reported taken from Ref. 128797.
