The pig-tailed macaque^[1] (Macaca nemestrina), also called the Sundaland pig-tailed macaque and Sunda pig-tailed macaque is a medium-sized macaque native to southern Thailand, Indonesia, and Malaysia.

• It is locally known as Berok. Pig-tailed macaques have light brown hair that covers their body and a white belly.
• The hair on the crown is dark brown or black in color and grows as if it has a depression in the crown. Males have mane-like hair around their faces.
• Pig-tailed macaques also have long legs and hairless snouts.
• These macaques are born black in color and change their color during adulthood. They are sexually dimorphic, with males being larger.
• Females are about half the size of males.

The Internal Journal of Primatology describes that the pigtail macaque feeds on^[¶]:

• Weeping Fig (Ficus benjamina).
• Council Tree (Ficus altissima).
• Plum Mango (Bouea oppositifolia).
• Styrax (Styrax benzoin)
• Pulasan (Nephelium lappaceum)
• Fig (Ficus)
• Apel En Wai (Syzygium jambos).
• Mango (Mangifera indica)
• Langsat (Lansium domesticum)
• Malabar Melastome (Melastoma malabathricum).
• Duhat (Syzygium cumini)

• Pig-tailed macaques get their name from their morphology. Their short, semi-erect tails resemble pigtails, earning them the nickname “pig-tailed” macaques.
• They live in groups with several males and females. The females stay with the natal troop, making it a female-bound society.
• Males are more socially dominant than females. However, groups of female species will gang up on a male species and attack him.
• Pig-tailed macaques are diurnal and spend most of their time in trees and only 8.4 percent^[2] on the ground.
• Some researchers refer to these macaques as silent monkeys because they seem so quiet.
