Etymology: Zebrasoma: Derived from Zebra = African horse + Greek, soma = body; referring to the stripes (Ref. 45335).
More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated, usually 8 - 35 m (Ref. 27115). Tropical; 23°C - 28°C (Ref. 27115)
Eastern Central Pacific: Line, Marquesas, Society, and Tuamoto islands to Pitcairn Group (Ducie Islands).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 21.0 cm TL male/unsexed; (Ref. 9710)
(total): 4 - 5;
soft rays: 19 - 24. Colour dark brown to nearly black (in life with faint irregular longitudinal bluish lines following scale rows). Snout protruding. Body depth 1.9 to 2.1 times in SL. Lower teeth with 5 denticulations, the central one twice as large as adjacent ones (Ref 9808).
Inhabits lagoon and seaward reefs (Ref. 33204). Benthopelagic (Ref. 58302). Its small and numerous pharyngeal teeth suggest a diet that consists mainly of filamentous algae (Ref. 33204).
