The Gibbon normally walks on Two Legs only, holding its arms up and out for balance, and is the only ape that does so.
Gibbons are apes in the family Hylobatidae, and can be found in tropical and subtropical rain forests in northeast India, Indonesia, China, and even the islands of Sumatra, Borneo and Java.
Also known as the lesser apes, gibbons are different from true great apes such as chimpanzees, bonobos, gorillas, orangutans, and humans because they are smaller and pair-bonded, do not making nests, and have some anatomical features which more closely resemble monkeys than great apes.
The Gibbon gets around by a technique called brachiation, swinging from branch to branch for long distances, and sometimes up to 35 mph.
They can also make huge leaps leaps of up to 26 feet, and walk bipedally with their arms raised for balance.
Of all tree-dwelling mammals, they are the fastest and most agile. Just be careful if you approach one.
Don’t piss it off.
