Lar Gibbon

Place to admire: Asia

Scientific name: Hylobates lar

IUCN-status: Endangered


The Lar Gibbon is found in Indonesia, Laos, Malaysia, Myanmar, and Thailand.

Here, it mainly lives in the treetops of tropical rain forests, mountain forests, diptocar forests, mixed deciduous and bamboo forests, and in evergreen deciduous forests.


The Lar Gibbon has a size of 42 to 58 centimeters with a weight between 4.5 and 7.5 kilograms. This species has a petite appearance, with very long arms and possesses no tail. Its fur has a variable color. It can be black, dark brown, light brown and sand colored. The hands and feet and the wreath of fur around the eyes, nose and mouth turn white. If the Lar Gibbon shows its teeth to you, you will see large dagger-like canines in both the upper jaw and lower jaw.


The diet of this species consists of various fruits, leaves, flowers, and insects.

Social behavior

The Lar Gibbon usually lives in pairs. They therefore form a close family. Every 3 years, the female usually gives birth to a young. Young does not reach adulthood until it is 4 to 5 years old, but it can live with the family for some time after that. Because of this, it is common to see a pair with 2 or even 3 young.

Every morning, just before or after sunrise, the Lar Gibbons sing a duet. They do this to defend their territory, to seduce another and to strengthen the pair bond.

Natural behavior

The Lar Gibbons are known as true swinging monkeys. Using their arms, they sway from branch to branch. Because they live and move mainly in the treetops, they have curved fingers, long hands, extremely long arms, and relatively short legs.

This species rarely touches the ground. If they touch the ground at all, they walk on 2 legs with their arms above their heads, to stay balanced.

The Lar Gibbon has a diversity of enemies such as Nebula leopards, Marble cats, Asian gold cats, Bengal tigers, Leopards, Pythons and Eagles.
