They spend most of their life in the trees. Gibbons cannot swim and avoid the water. LIFE SPAN Gibbons live about 35-40 years. The different species of gibbons live in different parts of southeast Asia, from China to the Malay peninsula, Burma, and North Sumatra. They are fully grown and able to reproduce at 12-13 years old.
Newborn gibbons are hairless except for a small cap of fur on the top of the head.
Female gibbons carefully nurture their young. Babies can grasp their mother's fur to cling to the mother's belly soon after birth. They are weaned at about 1 year old. Young gibbons stay with their mother for about 6 years. Gibbons are losing their natural habitat because human agriculture is encroaching on it.
