Because of the rapid deforestation of their habitats, gibbons are an endangered species. Gibbons have lightweight bones. Like all apes, they have no tail. Some species of gibbons have a white face ring, a band of white face completely surrounding their face. Their feet have five toes, including an opposable big toe.
Gibbons can grasp and carry things with both their hands and their feet.
SIZE Male gibbons are slightly larger than the females. They also eat insects, spiders, bird eggs, and small birds. Gibbons drink water, often by dipping a furry hand into the water or rubbing a hand on wet leaves, and then slurping up the water from their fur. Gibbons sometimes do this while dangling above the water from a thin tree branch. A gibbon family has a territory of about 30 to 50 acres of old-growth rain forest.
