Etymologie
Scarus : du Latin, scarus = scare, ou poisson de mer (scare est le nom vernaculaire générique des poissons-perroquets). Le mot latin est dérivé du Grec, skaros, de même sens. Les Grecs connaissaient cette famille à travers Sparisoma cretense (Linnaeus 1758), présent sur leurs côtes, Aristote en décrit les viscères. Le genre a été décrit la première fois par Pehr Forsskål en 1775.
spinus : du Latin, spina, -ae, = arête, os long et mince des poissons ou épine, excroissance pointue de certains animaux ou piquant, appendice acéré.

Biology
Inhabits coral-rich areas of outer lagoon and seaward reefs. Usually solitary. Females usually in small groups with a male nearby; they may mix with females of similar species. An uncommon fish patchily distributed through much of its range. Oviparous, distinct pairing during breeding. Feeds mainly on algae.
