Siamang Gibbon

Native to Malaysia, Thailand and Sumatra, these are the largest of the gibbons. They stand up to 1 metre (3 ft) tall and weigh up to 14 kg (30 lb). They are arboreal, living in forests up to elevations of 3800 metres above sea level.

Siamang Gibbons live in family groups consisting of one dominant male, a dominant female, their offspring and infants. Subadults leave the family group at an age of six to eight years. They are very social animals. The male will often carry an infant for a large portion of the day after it reaches an age of about one month.

They eat primarily fruit but also leaves, flowers and a few small animals and insects. Each group controls a home territory which does not overlap that of other groups.
