Orangutans are the only exclusively Asian genus of extant great ape. The largest living arboreal animals, they have proportionally longer arms than the other, more terrestrial, great apes. They are among the most intelligent primates and use a variety of sophisticated tools, also making sleeping nests each night from branches and foliage. Their hair is typically reddish-brown, instead of the brown or black hair typical of other great apes.

Native to Indonesia and Malaysia, orangutans are currently found only in rainforests on the islands of Borneo and Sumatra, though fossils have been found in Java, the Thai-Malay Peninsula, Vietnam and Mainland China. There are only two surviving species, both of which are endangered: the Bornean Orangutan (Pongo pygmaeus) and the critically endangered Sumatran Orangutan (Pongo abelii). The subfamily Ponginae also includes the extinct genera Gigantopithecus and Sivapithecus. The word "orangutan" comes from the Malay words "orang" (man) and "(h)utan" (forest); hence, "man of the forest".

The Singapore Zoo (Chinese: 新加坡动物园; pinyin: Xīnjiāpō Dòngwùyuán; Malay: 'Taman Haiwan Singapura'; Tamil: சிங்கப்பூர் விலங்குக் காட்சிச்சாலை), formerly known as the Singapore Zoological Gardens and commonly known locally as the Mandai Zoo, occupies 28 hectares (0.28 km²) of land on the margins of Upper Seletar Reservoir within Singapore's heavily forested central catchment area. The zoo was built at a cost of S$9m granted by the government of Singapore and opened on 27 June 1973. It is operated by Wildlife Reserves Singapore, who also manage the neighbouring Night Safari and the Jurong BirdPark. There are about 315 species of animal in the zoo, of which some 16% are considered threatened species. The zoo attracts about 1.6 million visitors each year.

From the beginning, Singapore Zoo followed the modern trend of displaying animals in naturalistic, 'open' exhibits with hidden barriers, moats, and glass between the animals and visitors. It houses the largest captive colony of orangutans in the world.^{[citation needed]} In 1977, primatologist Dr Francine Neago lived inside a cage with eighteen orangutans for six months to study their behavior and communication.

A primate ( /ˈpraɪmeɪt/ US dict: prī′·māt) is a mammal of the order Primates (/praɪˈmeɪtiːz/ US dict: prī·mā′·tēz; Latin: "prime, first rank"), which contains prosimians and simians. Primates arose from ancestors that lived in the trees of tropical forests; many primate characteristics represent adaptations to life in this challenging three-dimensional environment. All but a few primate species remain at least partly arboreal.
