It lives on Sumatra and the Malay Peninsula and moves by swinging from branch to branch with its very long arms.
It blows up a large pouch on its throat to make its voice ring out, and both males and females have this pouch.
A family made up of a male-female pair and their young holds a territory and announces it with loud calls.
How the Siamang lives
They wake at sunrise and call before setting out to find food. They eat fruit and young leaves, plus small amounts of insects, bird eggs and other foods. Adult males groom females and younger males. They sleep sitting upright in the fork of a tree.
