The Southern pig-tailed macaque[1] (scientific name: Macaca nemestrina[1]) is a species of monkey belonging to the Old World monkey family (Cercopithecidae).
It is short in stature with short, gray or brown fur. Its face is relatively long, with short gray or brown fur on its head that grows in a spiral pattern. The fur on its belly is pale, almost white, and the fur on its back is dark brown or black. Its tail is relatively short. Females are smaller and have less fur on their foreheads than males.
They live in evergreen forests at the foot of mountains. They are nomadic and don't stay in one place for long. Some forage alone and don't form groups. They prefer to live on the ground rather than in trees, but they sleep in trees. They like to make vocalizations and often call out in unison with their group. They begin breeding at 3–4 years of age and can breed in any season. The gestation period is about 5–7 months, and they give birth to one offspring at a time. Their lifespan is about 25 years. A male or individual monkey may mate with several other individuals and does not form a permanent pair.
These monkeys have smaller troops than other monkey species, typically no more than 40–45 individuals.
Their diet consists of fruits, seeds, and small insects. When eating, they usually store food in their cheeks and then gradually push it out with their hands to eat it little by little. # By Khao Sok The Turtle Bridge # Cheow Lan Lake # Khao Sok National Park
