About Siamangs

 
Siamangs are small black apes up to a metre in height and 14 kilograms in weight. They are found in the forests of Sumatra and Malaysia and are threatened with extinction due mainly to habitat removal for palm oil plantations.

Facts


Siamangs:
  • are diurnal (active in the day), arboreal (spend most of their time in the trees) and territorial
  • live in small groups consisting of a dominant adult male and female and their offspring
  • have a diet that largely consists of fruits and flowers and a small amount of insects
  • are important for forest regeneration as they carry seeds long distances and deposit them in their poo
  • are equipped with large canine teeth which they use for piercing the tough outer shell of forest fruits.

Typical Behaviours


Siamangs have large throat pouches which they can inflate to the size of their head, allowings them to make loud calls. They will call to their neighbours early in the morning and at times during the day.

Up to half the day can be spent resting, with feeding, moving, foraging, social activities, grooming and playing occupying the rest of the time.
