The white-handed gibbon is a tailless ape with exceptionally long forelimbs, hands, and feet adapted for swinging beneath forest branches. Individuals occur in two broad color forms: a dark coat varying from brown to black or gray, and a pale coat ranging from cream to light brown. Both forms have white hands and feet and a ring of short pale hair surrounding the bare face. Adults measure approximately 42–58.4 cm and weigh 4.4–7.6 kg, with males averaging slightly larger.

White-handed gibbons occupy the high canopy of Southeast Asian dipterocarp, lowland, submontane, seasonal evergreen, bamboo, and peat-swamp forests. They live in small, territorial social groups and travel principally by brachiation. Bonded adults produce long, coordinated duets that advertise their territory and may be heard about one kilometre away. The diet consists mainly of ripe fruit, supplemented by leaves, flowers, and insects. The opened source reports populations in Indonesia, Laos, Malaysia, Myanmar, and Thailand but states that the species is no longer found in China. (Animal Diversity Web)
