Being highly intelligent, wild long-tailed macaques can use different stone tools to aid in foraging. They can even use human hair as dental floss, as has been reported in Thailand, and have been observed catching fish with their bare hands in North Sumatra!

The long-tailed macaque is also called the crab-eating macaque.

Monkeys are social animals just like us. In the wild, they live in groups of 15-30 monkeys. Their social structure and behaviour are almost as complex as ours. Each monkey group (called a troop) is made up of a dominant male monkey, also known as the alpha male, and his harem of female monkeys. 

Monkeys spend a lot of time grooming each other. To them, this is an important social activity for developing friendships and strengthen social bonds.

Leave them alone. Watch them from a distance and respect their natural diet and their natural role in our forests by not feeding them.

Despite their name, crab-eating macaques typically do not consume crabs as their main food source; rather, they are opportunistic omnivores, eating a variety of animals and plants. Although fruits and seeds make up 60 - 90% of their diet.

Considered sacred animals at some Buddhist and Hindu temples. Some believe that the monkeys are the descedents of Hanuman, the monkey-hero of the mythical Hindu figure Rama.

Unlike chimps that use brute force to crack nuts, macaque hands are very dexterous and flexible. Just like humans, almost 70% are right handed.

One of the best primate swimmers. They can drop into water to avoid predators, such as clouded leopards and pythons, and prefer to sleep in trees overhanging water.
