Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Cuvier.
Environment / Climate / Range
Marine; reef-associated; depth range 3 - 25 m (Ref. 9710). Subtropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 120 cm TL male/unsexed; (Ref. 7251); common length : 70.0 cm TL male/unsexed; (Ref. 3802); max. published weight: 20.0 kg (Ref. 9710)
soft rays: 9. Fins dull orange with tongues of green extending into the dorsal and anal; margins of median fins blue; dental plates blue-green. There appears to be no obvious difference in color with sex (Ref. 13442).
Western Atlantic: Bermuda, Florida (USA), and the Bahamas to Argentina; absent in the northern Gulf of Mexico.
