Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Schultz.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 40 m (Ref. 90102), usually 20 - ? m (Ref. 9710). Tropical; 19°N - 24°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 48636)
soft rays: 9. Males recognized by the yellow pectoral fins, horizontal green band from tip of snout to above pectoral fin base and large individuals with oval yellow patch on caudal peduncle. Females plain yellowish grey with pale lines along abdominal area (Ref. 48636). Scales large. Median predorsal scales 4; 3 scale rows on cheek, ventral row with 1-2 scales. Truncate caudal fin in initial phase (slightly rounded); slightly lunate in terminal phase. Dental plates nearly covered by lips. Terminal males with 1 or 2 upward-projecting canines posteriorly on lower dental plate and 1 on upper plate. Large initial phase individuals are tan while terminal phase individuals have a distinctive transparent yellowish-tan pectoral fin (Ref. 1602).
Inhabits lagoon and channel reefs, usually deeper 20 m (Ref. 9710). Minimum depth of 2 m reported from Ref. 2689.
