The Bornean orangutan^[1] is native to the Borneo Island. Along with Pongo abelii (the Sumatran orangutan) and Pongo tapanuliensis (the Tapanuli orangutan), it belongs to the only genus of great apes endemic to Asia.

• They have thick, shaggy, orange-red hair and long arms, which are beneficial for traveling through the canopy.
• They grasp with their hands and feet, which suits their arboreal life. Unlike most mammals, their fur does not cover their faces.
• However, Bornean orangutans do have facial hair, including beards and whiskers.
• Also, they have sizeable fatty cheek pads called a harness and a drooping throat pouch.

The Bornean Orangutan consumes these plant matter^[¶]:

• Clustertree (Ficus racemosa)
• Brown-Woolly Fig (Ficus drupacea).
• Pulasan (Nephelium lappaceum)
• Jacareuba (Calophyllum brasiliense)
• Oriental Trema (Trema orientalis).
• Cowa Fruit (Garcinia cowa).
• Ilang-Ilang (Cananga odorata)
• Javanese Treebine (Cissus nodosa).
• Bishopwood (Bischofia javanica)
• Weeping Fig (Ficus benjamina).
• Fig (Ficus)
• Council Tree (Ficus altissima).
• Myrobalan (Terminalia bellirica)
• Argus Pheasant Tree (Dracontomelon dao).

• Although orangutans are not territorial, adult males exhibit threatening behavior when encountering other males and only socialize with females for mating.
• Like other great apes, orangutans are highly intelligent and display different tools and cultural patterns in the wild. In addition, orangutans share about 97 percent of their DNA with humans.
• The Bornean orangutan is an endangered species whose existence is seriously threatened by deforestation, hunting, and palm oil plantations.
• They travel more on the ground than their Sumatran counterparts despite being arboreal.
• The Bornean orangutan exhibits nesting behavior. Nests are built to be used during the day or at night.
