Also known as the Müller’s or gray gibbon, the Bornean gibbon[1] is native to the Bornean Island, which is divided between the nations of Brunei, Malaysia, and Indonesia.
- They have light brown fur that fades to black on the face, chest, and inner arms, with a white border around the face.
- They have padded buttocks and pronounced canines, and the base of the thumb unusually starts at the wrist rather than the typical palm of the hand, enabling them a wide range of motion.
- However, this limits their ability to grasp small objects. One of their most distinctive features is their incredibly long arms, especially their long ulna and forearms’ radial bones.
- This trait, along with many other minor skeletal adaptations, tailors the species to its method of locomotion: brachiation.
