Northern Pig-tailed Macaque

The northern pig-tailed macaque (Macaca leonina) is a vulnerable species of macaque in the subfamily Cercopithecidae. It is found in Bangladesh, Cambodia, China, India, Laos, Myanmar, Thailand, and Vietnam. Traditionally, M. leonina was considered a subspecies of the southern pig-tailed macaque (M. nemestrina), but is now classified as an individual species. In the 21st century, the pig-tailed macaque was split into the northern pig-tailed macaque species Macaca leonina and the Sundaland pig-tailed macaque species M. nemestrina. This reclassification was aided by the observation of sexual swellings and basic attributes that distinguish the two. The northern pig-tailed macaque is frugivorous and their social grouping is matriarchal, where sexual dimorphic traits can distinguish males and females. Wikipedia →
