Macaque Monkey, Sabah, Malaysia
Macaque monkey in the Sepilok Orang Utan Reserve in Sabah, Malaysia. The southern pig-tailed macaque (Macaca nemestrina) is a medium-sized Old World monkey. They are mainly terrestrial but they also are skilled climbers. Unlike almost all primates they love water. They live in large groups split into smaller groups during the day when they are looking for food. They are omnivorous, feeding mainly on fruits, seeds, berries, cereals, fungi and invertebrates. There is a hierarchy among males based on strength, and among females based on heredity. Thus, the daughter of the dominant female will immediately be placed above all other females in the group. The dominant female leads the group, while the male role is more to manage conflict within the group and to defend it. Sexual maturity is reached at the age of 3–5 years. Female gestation lasts about 6 months. She will give birth to one infant every two years. Weaning occurs at 4–5 months.
