As they swing along, the trunk and legs hang below giving the body an upright posture. A tail would just get in the way and be a nuisance to this type of locomotion.” “Gibbons can also walk bipedally along branches using their arms for balance. A tailless upright posture is also well suited to climbing tree trunks.”

Are gibbons tailless?
Like all apes, gibbons are tailless. Unlike most of the great apes, gibbons frequently form long-term pair bonds. Their primary mode of locomotion, brachiation, involves swinging from branch to branch for distances up to 15 m (50 ft), at speeds as high as 55 km/h (34 mph).
Gibbons are not monkeys. They are part of the ape family and are classified as lesser apes because they are smaller than the great apes. The great apes are bonobos, chimpanzees, gorillas, humans, and orangutans.

Are gibbons Brachiators?

Leafy plants, flowers, young leaves, new shoots, insects, and occasional birds’ eggs are on the white-handed gibbons’ menu, too. Diet varies with the seasons. In Thailand, for example, flowers are prevalent in the cool season, while ripe fruit is abundant during the hot, wet seasons.
