The agile gibbon (Hylobates agilis), also called the black-handed gibbon, is an Old World primate, and is a part of the gibbon family. It is native to Indonesia, specifically, on the island of Sumatra. The agile gibbon can also be found in Malaysia, and southern Thailand.

The Agile gibbon (Hylobates agilis), a is an endangered primate found in Southeast Asia. Like all gibbons, they move by swinging from branch to branch for distances up to 15 m (50 ft) and can also make leaps up to 8 m (26 ft), and walk bipedally with their arms raised for balance.

Agile gib­bons come in a va­ri­ety of dif­fer­ent col­ors, in­clud­ing black, brown, light tan and red­dish-brown. Both sexes have white eye­brows. Males and fe­males can be eas­ily dis­tin­guished by the white eye­brows and cheeks pos­sessed by the males. Gib­bons lack tails.

Agile gibbons, sometimes called black-handed gibbons, are widespread throughout Sumatra, northern Malaysia, and Southern Thailand. They live in evergreen and semi-deciduous forests, from lowland swamps to higher-elevation montane forests. They prefer high canopy elevation, sometimes as high as 4,593 feet (1,400 m).

Agile gibbons, also known as dark-handed or black-handed gibbons, are arboreal monkeys; they are always in the trees. Agile gibbons belong to the great ape family. However, they are categorized as lesser apes because they are smaller than great apes.

Within the submontane forests of the Batang Toru Forest Complex, agile gibbons have been documented to have home ranges over 50 ha (Nowak pers. obs.).

Agile gibbons are small apes, and, like all apes, they do not have a tail. Agile gibbons have white eyebrows and the males also have white furred cheeks. The coat varies in colour from black to pale golden brown. Like other gibbons, they have distinctive long arms and use a motion called brachiation to swing through the tree-tops.

The Agile Gibbon, also known as the Black-handed Gibbon, is a small arboreal primate found in the tropical rainforests of Southeast Asia. With a slender body and long limbs, it is well adapted for a life spent swinging through the treetops.

The physical prowess of the Agile gibbon is nothing short of astonishing. Their exceptionally long arms, when compared to their torso, along with their elongated fingers, are perfectly designed for brachiation.

At home in the tropical rainforests of Sumatra, the Agile Gibbon is well adapted to its life in the forest canopy with extremely long arms and fingers allowing it to swing from tree to tree via brachiation. Agile Gibbons can be a variety of colors from black to light brown and even tan.
