The green humphead parrotfish (Bolbometopon muricatum) is the largest species of parrotfish, growing to lengths of 1.3 m (4.3 ft) and weighing up to 46 kg (101 lb), though some sources report a total length of 1.5 m (4 ft 11 in) and weight of 75 kg (165 lb). It is the only species in the monotypic genus Bolbometopon. Fossil remains of Bolbometopon sp. are known from the Late Miocene of Sri Lanka.
Other common names include bumphead parrotfish, humphead parrotfish, double-headed parrotfish, buffalo parrotfish, and giant parrotfish.
It inhabits reefs in the Indian and Pacific Oceans, from the Red Sea in the west to Samoa in the east, and from the Yaeyama Islands in the north to the Great Barrier Reef, Australia, in the south. In regions that are not overfished, the humphead parrotfish is a prominent member of the ecosystem, whether through their social interactions or their feeding behavior.
