Six Things You Didn’t Know About The Lion-Tailed Macaque
The lion-tailed macaque is a rainforest dweller which spends a majority of its life in the upper canopy of tropical moist evergreen forests.
2. Not human friendly
Unlike other macaques, it avoids humans. It is a territorial animal, defending its area first with loud cries towards the invading troops.
It is believed there are just 3000-3500 of these animals scattered over several areas in Kerala, India. The lion-tailed macaque ranks among the rarest and most threatened primates.
A lion-tailed macaque can live to 20 years in the wild and sometimes 30 or more
years in zoos.
These monkeys use 17 different vocal patterns to communicate. They also communicate with body language, such as yawning with a grimace to indicate dominance or a threat, and smacking their lips to greet one another.
