Southern pig-tailed macaque
The southern pig-tailed macaque (Macaca nemestrina), also known as the Sundaland pig-tailed macaque and the Sunda pig-tailed macaque, is a medium-sized macaque that lives in Sundaland, southern Thailand, Malaysia, and Indonesia. It is known locally as beruk.
The species epithet, nemestrina, is an adjective (derived from Latin Nemestrinus, meaning "the god of groves") modified to agree in gender with the feminine generic name. M. nemestrina formerly included the northern pig-tailed, Pagai Island, and Siberut macaques as subspecies. All four are now considered separate species.
In the 19th century, bruh was the native name used by Malays in Sumatra for the macaque.
As with other Macaca species, males are larger than females; while males are measured at 50–58 cm (20–23 in) in length and 5–12 kg (11–26 lb) in weight, females are measured at 38–48 cm (15–19 in) in length and 4.5–6 kg (9.9–13.2 lb) in weight. This macaque has buff-brown fur, with a darker dorsal area and lighter ventral area. Its common name refers to the short tail held semi-erect, resembling the tail of a pig.
M. nemestrina is mainly terrestrial, but also a skilled climber. Unlike almost all primates, these macaques love water. They live in large groups that split into smaller groups during daytime when they are foraging. They are omnivorous, feeding mainly on fruits, seeds, berries, cereals, fungi, and invertebrates. A study in peninsular Malaysia found them to be the primary, and perhaps the only, seed dispersers of the rattan species Calamus calicarpus (syn. Daemonorops calicarpa) and Calamus castaneus.
There is a hierarchy among males, based on strength, and among females, based on heredity. Thus, the daughter of the alpha female will immediately be placed above all other females in the group. The alpha female leads the group, while the male role is more to manage conflict within the group and to defend it.
Female gestation lasts around 5.7 months. She will give birth to one infant every two years. Weaning occurs at 4–5 months. Sexual maturity is reached at 3–5 years.
In Thailand, they have been trained for 400 years to harvest coconuts.
