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 6 - 15 m (Ref. 90102). Tropical
Western Indian Ocean: East Africa, including Madagascar, Seychelles, and Mauritius to the south coast of India and Sri Lanka. Absent from the Red Sea (probably replaced by Scarus fuscopurpureus) and Persian Gulf. Presence in Somalia to be confirmed (Ref. 30573). Eastern Indian Ocean: Similan Island, Thailand (Ref. 9710).
