Also called the lesser apes, among other differences, gibbons are smaller than the great apes (chimpanzees, gorillas, orangutans and humans). Gibbons are masters of brachiation, allowing them to swing from branch to branch distances of up to 50 feet, at speeds as much as 35 mph. They occur in tropical and subtropical rainforests from northeast India to Indonesia and north to southern China.
Orangutan is derived from the Malay orang hutan meaning man of the forest. Orangutans are the most arboreal and solitary of the great apes, spending nearly all of their time alone in the trees. They are highly endangered and found only in the rainforests of the islands of Borneo and Sumatra.
The largest primate, male gorillas range in height from 1.65 m to 1.75 m, and in weight from 140 kg to 165 kg. Females are about half the weight of males. A dominant "silverback" male leads a group of his females and offspring. This male determines group movement, mediates conflicts, is a playmate for his young and often a lifelong mate for his females. Gorillas inhabit the forests of western and central Africa.

Chimpanzee is the common name for two species in the genus Pan. The Common Chimpanzee (P. troglodytes) is found in West and Central Africa. The bonobo (P. paniscus), is found in the forests of the Democratic Republic of the Congo. Anatomical differences between Common and bonobos are slight, but in sexual and social behaviour there are marked differences.
