Black-handed gibbon
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. They are the fastest of all tree-dwelling, nonflying mammals.

starts withThe Agile gibbon has fur varying in color from black to red-brown. The brow is white, and the male can be recognized by his white or light-grey cheeks. Like all gibbons, it is tailless. The male is slightly larger than the female.
Agile gibbons are found on Sumatra southeast of Lake Toba and the Singkil River, in a small area on the Malay Peninsula, and in south Thailand near the Malaysian border. They typically live in rainforests and in swamp forests and can be found both in lowland and mountainous areas.
Agile gibbons are arboreal meaning they live in trees and rarely come to the ground. With their long arms they swing on branches, brachiating at a fast pace. Agile gibbons live in mated pairs in a strictly enforced territory, which is defended with vigorous visual displays and songs. Agile gibbons are diurnal and early in the morning, they start their days with great calls that can be heard throughout the upper canopy.
Agile gibbons are herbivores primarily frugivores and eat a wide viriaty of fruits. However, they also consume leaves, flowers, and sometimes insects.
Agile gibbons are monogamous and form pairs that remain together for life. They can breed at any time of the year. Females give birth to a single offspring after 7 months' gestation. The infant is weaned at barely 2 years of age and when fully mature, at about 8 years, it leaves its family group in order to look for a mate.
Agile gibbons are threatned by the continuing loss of their native habits due to forest conversion, agricultural expansion, logging, mining, road development. Agile gibbons are also heavily captures for the pet trade.
The IUCN Red List and other sources don’t provide the number of the Agile gibbon total population size. Currently, this species is classified as Endangered (EN) on the IUCN Red List, and its numbers today are decreasing.
Due to their frugivorous diet, Agile gibbons help disperse the seeds of various fruits thus aiding in forest regeneration.
