Quick answer
Key facts about white-handed gibbon — size, diet, habitat, and conservation in one place.
Brachiation masters
Gibbons are the fastest arboreal mammals, swinging beneath branches on long arms with ball-and-socket wrist joints. They rarely descend to ground — territorial songs advertise presence from the canopy.
Duet songs
Mated pairs sing coordinated duets at dawn — males and females have distinct phrases that reinforce pair bonds and warn neighbouring groups. Songs carry over a kilometre through forest.
Monogamous families
Gibbons typically pair for years, raising one offspring every 2–3 years. Juveniles stay with parents until sexual maturity, learning songs and foraging routes.
Deforestation threat
Listed Endangered, white-handed gibbons lose habitat to palm oil and logging. Thai and Malaysian protected areas and rehabilitation centres support remaining wild groups.
