Updated July 30, 20261 min readCited sources

Gibbons are small apes in the family Hylobatidae, native to tropical and subtropical forests of Southeast Asia. They are known for their long arms, tailless bodies, and agile brachiating movement through trees.

What it is

Gibbons are lesser apes, not monkeys, and belong to the primate family Hylobatidae. There are about 20 living species across four genera: Hoolock, Hylobates, Nomascus, and Symphalangus. They are the smallest apes and are adapted entirely to life in the trees.

Key details

Gibbons move primarily by brachiation — swinging hand over hand from branch to branch. They are diurnal, live in small territorial groups, and are mostly fruit-eaters, though they also eat leaves and insects. Many species produce loud, complex vocalizations used for communication and defending territory.

Why it matters

Gibbons are a distinct branch of the ape family, offering insight into primate evolution and arboreal adaptation. Their vocal behaviour is among the most elaborate in mammals, and their forest habitats across Southeast Asia are increasingly threatened by deforestation and human activity.

In short

  • Gibbons are apes, not monkeys, and belong to family Hylobatidae.
  • They move by brachiation and live in small territorial groups.
  • About 20 species exist across four genera in Southeast Asia.
  • Their loud, musical calls are used for communication and territory defence.
