Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 18 m (Ref. 9710). Tropical; 30°N - 24°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 48636)
soft rays: 9. This species is distinguished by the following features: 6 median predorsal scales; 3 scale rows on cheek 1(5), 2(5-6), 3(2); lips largely covering the dental plates; caudal fin is truncate to slightly rounded. Colour overall is green to purplish or bluish, sometimes a pink patch on pectoral region, often with lime-green saddle on upper caudal-fin base, a dark green 'moustache' and pale green patch on cheek (Ref. 90102).
Inhabits coral-rich areas of outer channels and seaward reefs (Ref. 9710). Occurs singly or in small groups (Ref. 9710) over intertidal flats to graze on algae during high water mark (Ref. 48636).
