Scarus

Scarus is a genus of parrotfish. With at least 52 currently recognised extant species, it is by far the largest genus in this group. The vast majority are found at reefs in the Indo-Pacific, but a small number of species are found in the warmer parts of the eastern Pacific, and the western and eastern Atlantic. Most are very colourful, and have strikingly different initial (males and females) and terminal (males only) phases. Most species have a maximum length between 30 and 50 cm (12 and 20 in), but the rainbow parrotfish (Scarus guacamaia) reaches 1.2 m (3.9 ft).
