The gibbons are the fastest canopy living primates. Leaping with their hind limbs is rare for gibbons. They use their arms to go greater distances. Unlike monkeys, their chests are broad instead of deep. Their shoulders have a great range of movement and powerful muscles. Hanging on one arm, a gibbon can rotate through 360 degrees. There are seventeen species of gibbons in the rain forest of South Asia.
    Unlike howler monkeys or the whoop-gobbling mangabey, in order to protect their resources, gibbons defend fixed home ranges of about 20 to 50 hectares. They largely depend on fruit trees for food. Gibbons enjoy a diet of pulpy ripe fruit, although they will supplement with leaves.
    It pays for the gibbons to stay in one place where food sources and routes are known to them. Gibbons live for 20 to 30 years and choose a mate for life.
