Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on authors: Bloch & Schneider.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 25 m (Ref. 9710). Tropical; 33°N - 8°N, 98°W - 59°W
Western Central Atlantic: Bermuda, Florida (USA), and Bahamas to northern South America; throughout the Caribbean Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 61.0 cm TL male/unsexed; (Ref. 7251); common length : 32.0 cm TL male/unsexed; (Ref. 3802)
soft rays: 9. Young adults of both sexes dark gray overall, with broad white stripe slightly below mid-side. Super males have upper pectoral fin margin and upper and lower margins of tail dusky with submarginal band of brownish orange (Ref. 26938).
Inhabits coral reefs and adjacent habitats. Feeds on algae scraped from rocks or dead coral. Sleeps in a mucus cocoon (Ref. 9710). Often seen in groups of one super male with several young adults, most of which are probably females (Ref. 26938). A protogynous hermaphrodite (Ref. 55367).
