Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 25 m (Ref. 9710). Subtropical; 33°N - 40°S, 98°W - 31°W
Western Atlantic: Bermuda, Florida (USA), and the Bahamas to Argentina; absent in the northern Gulf of Mexico.
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).
Inhabits coral reefs. Young are commonly found in mangrove areas. Feeds mainly on benthic algae (Ref. 3802). Known to have a home cave to which it retires at night or when danger threatens; makes use of the sun as an aid to locating the cave.
