Siamangフクロテナガザル
Symphalangus syndactylusEN— Endangered
The siamang is the largest of the gibbons, a black-furred ape native to the forests of Sumatra and the Malay Peninsula. It is famous for its inflatable throat pouch, which it uses along with its mate to perform loud, coordinated duet calls that reinforce their monogamous pair bond. Classified as Endangered by the IUCN, it faces mounting pressure from habitat loss to palm oil plantations and the illegal pet trade.

Did You Know?
- The siamang is the largest of all gibbon species, weighing roughly twice as much as other gibbons. Source
- Both sexes have a large throat pouch that can inflate to nearly the size of their own head, allowing them to produce loud, far-carrying calls. Source
- Siamangs are typically monogamous, and mated pairs strengthen their bond through loud, well-patterned duet calls. Uniquely among gibbons, two toes on each foot are partially joined by a membrane. Source
