There are 5 subspecies of white-handed gibbons. Their hands and feet are white or pale white, hence the name white-handed gibbons.

The population of white-handed gibbons generally consists of 5-8 members in a family, including one adult male and one adult female, and the rest are semi-adult and young gibbons, with an adult male as the leader. Gibbons have a relatively long maturity period, and family relationships are not only stable, but also harmonious and friendly. Family members are generally very harmonious, caring for each other and defending each other.

The habits of the white-handed gibbon are similar to those of the black gibbon. They live a family life with male and female spouses and are territorial. The territory of each group is about 54 hectares, but they only forage within an area of 1.5 square kilometers in a day. During the day, they use their arms to climb branches and swing and jump on trees 20-30 meters high in the forest, using both their front and back limbs at high speed. Due to the high characteristics of this movement, they often change the direction of their chest and arms. Long-term evolutionary adaptation has made the sides of their shoulders flat, instead of being wider like monkeys. Their elbows are longer and can rotate 360 degrees in all directions. They can move forward and backward quickly, and their feet only play the role of assisting pedaling. They have keen hearing and smell, are timid, and afraid of cold.

Calling is the main way for members of the white-handed gibbon group to communicate. Every morning, males and females cry in chorus, or in a rhythmic, or sad and low voice, or make intervals similar to blowing bubbles. The male's call is sandwiched between the female's call, and at the end of the call, a tail sound is added.

The white-handed gibbon lives in tropical and subtropical dense forests. It mainly lives in the southern subtropical monsoon evergreen broad-leaved forests, generally at an altitude of 1000-2000 meters.

The hair on the whole body is dense and long, relatively fluffy, and all of them are brown-yellow. The color varies between different subspecies. The face is brown-black, but the hair on the hands and feet is very light, almost white when viewed from a distance, so it is also called the white-handed gibbon. In addition, there is a circle of white hair from the edge of the eyebrow through the cheek to the lower jaw, which outlines the face very strikingly. The legs are short, the palms are longer than the soles of the feet, and the finger joints are long; the body is slender, the shoulders are wide and the hips are narrow; there are long canine teeth. There are calluses on the hips, no tail and cheek pouches. There is a sound bag in the throat, and it is good at singing.
A clear white facial ring is often formed around the face. The facial ring of females is almost closed, while that of males is mostly not closed (interrupted by white eyebrow lines). Both sexes have dark and light co
