Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 20 m (Ref. 9710). Tropical
Western Indian Ocean: East Africa south to Natal, South Africa; also around islands of the western Indian Ocean.
