Climbing around and playing with cute baby gibbons

About 20 species of gibbons live in Southeast Asia's tropical forests. Gibbons have a human-like build and lack a tail, but seem to lack the higher cognitive abilities of great apes (gorillas, orangutans, chimpanzees, and bonobos).Their arms are longer, they have dense hair, and their throat sac enhances sound. Gibbon voices are loud, musical in tone, and carry over a long distance.
