The name Orangutan can be translated to "man from the forest". In the Malay language (the official language of Malaysia and Indonesia) "orang" means man and "hutan" means forest. Today the orangutans are only found on the islands of Sumatra and Borneo, but once they probably inhabited all of South-East Asia. Their natural habitat is the rainforest, and in contrast to other great apes they spend most of their life in the trees.
