How many white-cheeked gibbons are left?
A “substantial” population of 455 critically endangered northern white-cheeked crested gibbons has been recently found living in the Pù Mát National Park in Nghệ An Province, northern Vietnam, near the border with Laos. Conservation International report they are living at high altitudes, and far from human settlements.
What is special about the hands of a white-cheeked gibbon?
Adaptation. Being brachiators, their hands are specially adapted so that they don’t grasp the branches while swinging from one to another; instead, they form a loose hook around the branches which helps them in the swinging. Their hands are also long, and the arms elongated, further facilitating the swinging motion.
How do white-cheeked gibbons protect themselves?
They defend about three-quarters of their range as their group territory. Defense takes the form of calls from the center of the territory, calls from the boundaries, confrontations across the boundaries, chasing across the boundaries and, rarely, physical contact between males.
Why do white-cheeked gibbons have long arms?

Is a chimpanzee stronger than a man?
Chimpanzees do have stronger muscles than us – but they are not nearly as powerful as many people think. This result matches well with the few tests that have been done, which suggest that when it comes to pulling and jumping, chimps are about 1.5 times as strong as humans relative to their body mass.
