Primates

The Hylobatidae family is made up of gibbons ['gi-b&n] and siamangs ['sE-&-"ma[ng]], both of which have very elongated arms, and both their forefeet and hindfeet are logn and thin. Their forefeet have a deep cleft between first and second digits. They swing through the trees using a form of locomotion called brachiation. Hylobatidae are medium in size and they lack tails. Some gibbons and siamangs have an enlarged throat sac, which inflates and serves as a resonating chamber when the animals call.
