Orangutans are the only exclusively Asian genus of extant great ape. The largest living arboreal animals, they have 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.

 

Orangutans are currently found only in rainforests on the islands of Borneo and Sumatra

The word "orangutan" comes from the Malay words "orang" (man) and "(h)utan" (forest); hence, "man of the forest".

Orangutans live a more solitary lifestyle than the other great apes. Most social bonds occur between adult females and their dependent and weaned offspring.

Resident females live with their offspring in defined home ranges that overlap with other adult females, who may be their relatives like mothers and sisters.

One to several resident female home ranges are encompassed within the home range of a resident male, who is their primary breeder.

During dispersal, females tend to settle in home ranges that overlap with their mothers. However, they do not interact when them any more than the other females and they do not seem to form bonds though affiliation, grooming, or agonistic support.
