The translation of the Malayan word "Orang-utan" is "forest man". And indeed do the large Great apes show a lot of human characteristics concerning their facial expression as well as their gestures. Adult male Orang-utans (Pongo pygmaeus) are imposing figures with their reddish shaggy fur, broad cheeks and long beards. In the wild they reach weights up to 80 kg. Male Orang-utans living in zoos and suffering from lack of exercise are often even heavier. Female Orang-utans are much smaller than the males. The face of young Orang-utans is fair-skinned but, like in Chimpanzees, gets darker the older they get.
Which zoos have them?Brookfield Zoo (United States) and Los Angeles Zoo (United States)
The Orang-utan is listed as Endangered (EN), considered to be facing a very high risk of extinction in the wild, on the IUCN Red List of Threatened Species
