DESCRIPTION OF THE SPECIES
Siamangs are the biggest and the darkest representatives of the Hylobatidae family, which may be found in the mountain forests. The body length is 71-90cm, the weight is about 10kg. They differ from the other representatives of the family with the distinctive gular sac (which intensifies the primate’s singing) and the availability of the membranes on the hind legs (unlike the other representatives of the family, siamangs are good swimmers). The siamang’s body is covered with the long, thick, shaggy hair of black colour. The animals have light mustache and beard, dark eyes, small nostrils and coal-black skin. They don’t have a tail. Their hands are 2.3-2.6 times longer than their body and their spread reaches 1.5m, which is very useful for the tree life. They live in constant couples. Siamangs are in the IUCN Red List as endangered (EN).
Siamangs eat young sprouts of plants, leaves and fruits.
They live for about 25 years, the record is 40 years.
