HAINAN GIBBON
Nomascus hainanus
DESCRIPTION
The Hainan Gibbon is a small, arboreal primate characterized by its long arms and a distinctive coat of black fur with a white face and throat. This species is known for its loud, melodic calls that can be heard over long distances, which they use to communicate with one another. They are highly social animals, often found in small family groups, and are primarily active during the day, spending most of their time in the treetops of their forest habitat.
FUN FACTS
- Hainan Gibbons are one of the rarest primates in the world, with their population dwindling to just a few dozen individuals
- They are also known for their unique vocalizations, which can be heard up to 2 kilometers away, making them one of the loudest primates
- | These gibbons are highly adapted to life in the trees, with long arms that allow them to swing gracefully from branch to branch
