The tail of the pig-tailed macaque is short and slender, slightly curled, and can be thinly furred or completely naked.
Pig-tailed macaques live in troops comprised of as many as 80 monkeys and are adept foragers.
Pig-tailed macaques are one of the largest of the small primates and are comparable in size to the rhesus macaque. They live in northeastern India and southern China as well as Burma, Laos and Cambodia.
