Meet the Orang-utanArticle | Updated 1 years agoPongo pygmaeus and Pongo abelii The orang-utan (meaning “person of the forest” in the Malay language) is native to Indonesia and Malaysia, but due to severe habitat loss, is now restricted to the rainforests of Borneo and Sumatra. There are two species of orang-utan – Pongo pygmaeus (the Bornean orang-utan) and Pongo abelii (Sumatran orang-utan). Can you spot both of the orang-utans in this tree? Image copyright WA Museum Orang-utans have red-orange hair and long, powerful arms. Males can weigh up to 90 kg, and females can reach up to 50 kg. Individuals generally lead solitary lives and have life spans of up to 50 years in the wild. They forage for fruits in the rainforest canopy, including jackfruit, lychees, mangoes and figs. Orang-utans will also supplement their diets with leaves, insects, soil, bark, eggs and small vertebrates.

Selective and illegal logging and habitat loss, clearing for agriculture and the palm oil industry, road development, mining, the illegal pet trade, and fires are all major threats towards orang-utans.
