Orangutans are intelligent and intriguing primates inhabiting the earth. These great apes are native to the fertile rainforests of Borneo and Sumatra and are characterized by solitary habitat, extensive lifespan, and extensive tool use. They are known as "person of the forest," which is an ideal name considering their arbor style of life and their strong attachment to the trees that they call their home.
Orangutans have a long history dating back to millions of years ago when fossil records indicate that their ancestors used to build an expansive range over the Asian continent. There are three extant species today: the Bornean (Pongo pygmaeus), the Sumatran (Pongo abelii), and the recently discovered Tapanuli (Pongo tapanuliensis); each has its own distinctive features and conservation requirements.
Orangutans are very intelligent. They fish using sticks when catching termites, use leaves as umbrellas, and even make crude feeding gadgets. Their memory enables them to follow trees that produce fruit when there is a season; this is necessary to survive in the wilderness. Although these animals are intelligent, they are mostly solitary, and the females of the species give birth to children alone for up to seven years.
