The orangutans are the two exclusively Asian species of extant great apes. Native to Indonesia and Malaysia, orangutans are currently found only in the rainforests of Borneo and Sumatra. Classified in the genus Pongo, orangutans were considered to be one species. However, since 1996, they were divided into two species: the Bornean orangutan (P. pygmaeus) and the Sumatran orangutan (P. abelii).
