Scarus globiceps, commonly known as the globehead, violet-lined, speckled or roundhead parrotfish, is a marine fish native to the Indian and Pacific Oceans, where it lives in coral reefs. French naturalist Achille Valenciennes described the globehead parrotfish in 1840. The species was the first parrotfish collected by Charles Darwin—from the waters around Tahiti and then from the Cocos Islands; the former was described as a new species and given the name Scarus lepidus by Leonard Jenyns, while the latter was confirmed as the current species. In 1900, Henry Weed Fowler described a specimen from Caroline Island as Scarus pronus, which was later synonymised with this species.
