The lar gibbon, also known as the white-handed gibbon, is an endangered primate in the gibbon family, Hylobatidae. It is one of the better-known gibbons and is often kept in captivity. Lar gibbons are social, diurnal and arboreal animals. On average, 15.5 hours are spent up in 'sleeping trees', from a few hours before dusk comes, until the following morning, a behavior which is an adaptation to minimize risk of predation. They are omnivores who mostly eat fruit. Additionally they eat plants, birds, bird eggs, and bugs. Predators to lar gibbons include leopards, tigers, pythons, and eagles. They may mob and chase off potential predators.
