Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Kner.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 25 m (Ref. 9710), usually 2 - 15 m (Ref. 37816). Tropical; 30°N - 24°S
Pacific Ocean: Christmas Island in the eastern Indian Ocean (Ref. 30874), then from the Philippines to Samoa, north to the Ryukyu Islands, south to the southern Great Barrier Reef.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 2334)
soft rays: 9. Males distinct and head looks bright yellow underwater; females drab with white teeth and some pale spots (Ref. 48636). Scales large. 4 median predorsal scales; a transverse pair of smaller scales which overlap medially in mid-dorsal line located directly anterior to 1st median scale; 3 scale rows on cheek, lower row with 1-2 (usually 2) scales. Caudal fin slightly rounded to truncate in initial phase; moderately to deeply emarginate in terminal phase. Adults in initial phase without canines on upper plate, 1 on lower; terminal-phase fish with 1-2 canines on upper and lower plates. Lips largely or entirely cover dental plates.
Inhabits coral-rich areas of outer lagoon and seaward reefs (Ref. 9710). Usually solitary (Ref. 9710). Females usually in small groups with a male nearby; they may mix with females of similar species (Ref. 48636). An uncommon fish patchily distributed through much of its range.
