Blue-barred Parrotfish

This species is blue-green to green in colour and commonly grows to approximately 46 cm. Its appearance is variable. It may have a central stripe on the dorsal and anal fins that is pink in color. The underside of the body may be pinkish or yellowish. There may be blue markings around the area of the pectoral fin.

Scarus ghobban is widespread throughout the Indo-Pacific, known from East Africa to Indonesia. It is also present in the Eastern Pacific, occurring in the Galápagos Islands as well as Japan, south to Australia and east to French Polynesia. Recently recorded in 2001 for the first time in the Mediterranean Sea off Israel, following an entry via the Suez Canal, it is now expanding northward in Levantine waters where it remains rare. Like other reef fish with a pelagic larval phase, regional currents facilitate high levels of gene flow, which in turn create high genetic diversity among the species.

Scarus ghobban grows quickly and can live up to 13 years. It tends to congregate in small schools. Scarus ghobban can rotate their mandible bone at a high velocity; this allows them to function as a scraper and facilitate hydrological transport of fine sediments.
