The Siamang gibbon apes derives its scientific name syndactylus from having joined digits on every foot. They possess a gular sac which is a throat pouch that allows them to make loud calls. The Siamang gibbon ape can inflate the size of the pouch to various sizes depending on the type of sound they want to make. Their arms are longer than their legs which help them to leap from one tree to another. The Siamang gibbon ape hair is dense, shaggy and darker than all other gibbons. They do not have hair on their face apart from a moustache.

The Siamang gibbon apes feed mainly on plants. When there is plenty to choose from, the Siamang gibbon ape feeds on ripe fruits rather than the unripe ones, and they always prefer young leaves to old ones. They also feed on animals and flowers. They eat only the petals of a large flower but will eat all parts of the small flowers. The Siamang gibbon ape peel out the fruit and discard the seeds.

The Siamang gibbon apes lives in families consisting of a male, female and infants. It is also possible to come across a Siamang gibbon ape group with a sub-adult among them. The sub adult eventually leaves at the age of six to eight years to start up a family. The sub-adult females leave their families earlier than the males. Their gestation period is 6 to 7 months 10 days. The female Siamang gibbon ape are in charge of taking care of the infant for the first year after it is born. After that, the males take up the role of caring for the infant until it is three years old. During this period, the males carry it in case they are traveling for a long journey, only returning to the females to nurse and sleep.

Many of the Siamang Gibbon Apes are known to lead a monogamous lifestyle, and they spend a lot of time with their mates. Researchers have however discovered that they are both polyandrous and monogamous group in the South Sumatra region. The infants from monogamous families receive more care and attention than those from polyandrous groups.

These Siamang Gibbon Apes spend a large part of the day resting after which they feed, move around and engage in social activities. The Siamang gibbon ape lie on their backs or stomach on top of large trees when they are resting. The adult males enjoy grooming more than the females and, therefore, take the lead when the time arrives. Grooming is important for the species for it helps them to enhance their social interactions.

The Siamang gibbon apes are located in the Sumatra Island and Malay Peninsula. They are widely distributed from the lowlands forests to mountain forests. The Siamang gibbon ape have also been sighted in some of the rain forests. Their home covers a range of 25 miles (40km), and they mark their territory every morning
