In the family of gibbons, the little apes, the Siamang is the largest and most vociferous species. In the wild, you will find it on Sumatra and the surrounding islands. Siamangs have a black, bushy coat, long swinging arms with a span of about 1.5 meters and relatively short hind legs with grip feet. They move in high treetops of the Southeast Asian rainforest and rarely come to the ground.
They mark their territory by very loud and miles-reaching chants. These consist of complex duets of the male and the female and even have pair-binding functions. Siamangs can live up to 30 years old. They become sexually mature between the fourth and fifth year of life and after eight months, give birth to a young, which is nursed for about 20 months. At puberty, the young leave the territory of the parents. Siamangs are listed as endangered by the World Conservation Union, IUCN. This is mainly due to the loss of habitat through deforestation, and in small part due to the hunt for the animals.
