Orang Utan means 'person of the forest' and this Asian ape is indeed truly a tree-dweller. Recent genetic evidence has led to the re-classification of Bornean and Sumatran orang-utans as separate species: Pongo pygmaeus and Pongo abelii respectively. Orang-utans have distinctive body shapes with very long arms that may reach up to 2m in length. They have a coarse, shaggy reddish coat and grasping hands and feet. They are highly sexually dimorphic, with adult males being distinguished by their large size, throat pouch and flanges on either side of the face, known as cheek pads. Native to Indonesia and Malaysia, they are currently found only in rainforests on the islands of Borneo and Sumatra. Orang Utan 紅毛人猿與人類基因相似度高達90％以上，而它與猴子最大的不同，在於它沒有尾巴，所以不會跳躍。雖然不能像猴子那樣靈活的在樹與樹之間跳躍，Orang Utan卻是攀爬高手。 Orang Utan主要分布在婆羅洲和蘇門答臘的低地森林地區，偏向素食，偶爾會吃昆虫。它們擁有很高的智慧，懂得分辨超過200種的可食植物，還會在樹上搭建供自己棲息的巢。 Orang Utan很少到地面喝水，它們都從樹洞取得水源。雄性Orang Utan的體積比雌性大一倍，一般的高度是5尺高，200磅重。它們的手比腳長一倍，而且很強壯，手腳都可以拿東西，很適合生活在樹上。
