These very acrobatic primates live in southeast Asia. Because they are so dextrous while moving in the trees, almost no predators can catch them. There are nine species of gibbons, including the siamang , which is the largest and darkest gibbon. 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.
