It is hard to guess what a Tonkin snub-nosed monkey weights. But we have the answer:
An adult Tonkin snub-nosed monkey (Rhinopithecus avunculus) on average weights 9.09 kg (20.03 lbs).
The Tonkin snub-nosed monkey is from the family Cercopithecidae (genus: Rhinopithecus). When reaching adult age, they grow up to 56.9 cm (1′ 11″). Usually, Tonkin snub-nosed monkeys have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The Tonkin snub-nosed monkey or Dollman’s snub-nosed monkey (Rhinopithecus avunculus) is a slender-bodied arboreal Old World monkey, endemic to northern Vietnam. It is a black and white monkey with a pink nose and lips and blue patches around the eyes. It is found at altitudes of 200 to 1,200 m (700 to 3,900 ft) on fragmentary patches of forest on craggy limestone areas. First described in 1912, the monkey was rediscovered in 1990 but is exceedingly rare. In 2008, fewer than 250 individuals were thought to exist, and the species was the subject of intense conservation effort. The main threats faced by these monkeys are habitat loss and hunting, and the International Union for Conservation of Nature has rated the species as “critically endangered”.
