The Bornean Orangutan (Pongo pygmaeus) is a great ape and a primate mammal.
The Bornean Orangutan has long reddish-brown fur and grey-black skin. It has long, strong arms, with short, bowed legs, and no tail. It has large cheek flaps of fatty tissue. Its hands have four long fingers and an opposable thumb, like the hands of a human, but their fingers are curved with a hooked grip. Its feet have four long toes with an opposable big toe, which humans do not have.
It measures about 115-137 centimetres (45-54 inches) tall. Its arms are about 200 centimetres (78 inches) long.
The Bornean Orangutan is native to the rain forests of Borneo. It is arboreal, living in trees.
It is not a knuckle-walker, like a chimpanzee; the Orangutan is a fist-walker – walking on its fists. It does not swim.
The Bornean Orangutan eats fruit, bark, honey, insects, and bird eggs. Its main predators are crocodiles.
It is an intelligent, solitary ape.
It builds a nest in a tree. The female Bornean Orangutan is pregnant for 9 months, before giving birth to one young. It is usually eight years before she has her next baby. The mother will carry her baby on her belly for the first four months. When the baby is about two years old, it will hold hands with other Orangutans, as they travel around.
It lives, on average, for about 30 years.
