Tonkin snub-nosed monkey

The Tonkin snub-nosed monkey (Rhinopithecus avunculus) is a primate species found in the tropical forests of northern Vietnam. It is characterized by its black upper body, striking white underside and face, and greenish face with prominent red lips. This species is the smallest among the snub-nosed monkeys and possesses a long tail and slender fingers and toes.1

These monkeys are leaf-eaters, also consuming flowers and fruits. They are known to live in small groups, but their rarity may contribute to this observation. Unfortunately, the Tonkin snub-nosed monkey is critically endangered, with a population estimated to be below 250 individuals. Habitat loss and lack of effective protection pose significant threats to its survival.1
