Description
The siamang, the largest of the gibbons, is distinguished by its throat, which expands significantly when it sings. This vocal sac amplifies their powerful calls, used to mark their territory and strengthen social bonds. On the ground, they move by walking on two legs, while in the trees, they swing from branch to branch using only the strength oftheir arms, a technique known as brachiation.
Threats and preservation
The siamang is endangered due to habitat destruction caused by logging and agriculture,as well as poaching for the trade of babysiamangs. The French organization “Kalaweit” is conducting conservation efforts in Indonesia, managing rehabilitation centers in Kalimantan and Sumatra, where over 300 primates rescued from the illegal trade are cared for and reintroduced into the wild.
