Parrot fish are a group of fish that have traditionally been regarded as family (Scaridae), but is now often considered a subfamily (Scarinae) from fish rivet. They are found in relatively shallow seas of tropical and subtropical regions throughout the world, but with the greatest species richness in the Indo-Pacific. About 90 species found in coral reefs, seagrass beds and rocky beaches, and play an important role in bioerosion.

Cockatoos are named for their teeth, which is also different from the other Labrids. Many of their teeth arranged in a dense mosaic on the external surface of the jawbone, forming a parrot-like beak with which they rasping algae from coral and other rocky substrates (which contribute to the process of bioerosion).

Although they are considered herbivores, parrot fish eating coral reef organisms, and it is important to note that they need not be vegetarian. Species such as parrots green humphead (Bolbometopon muricatum) including corals (polyps) in their diet they are feeding activity is important for the production and distribution of coral sand on the reef biome and can prevent algae from choking coral .. Teething continues, replace the material worn by the pharyngeal teeth grinding feeding.The rock fish ingests during the meal. After they digest them out like sand stone helps create small islands and sandy Caribbean beaches. One cockatoo can produce 90 kg of sand every year.

Maximum size varies within the family, with the majority of species reach 30-50 cm (12-20 in) in length. However, very few species reach nearly 1 meter (3.3 feet), and green parrotfish humphead reach up to 1.3 meters (4.3 feet).

Their deep body, with large, thick cycloid scales, pectoral and caudal fin large homocercal.

Cockatoo using their breasts as their primary means of power, involved pieces just to reach higher speeds.
