How many baby Tonkin snub-nosed monkeys are in a litter?
A Tonkin snub-nosed monkey (Rhinopithecus avunculus) usually gives birth to around 1 babies.
Each of those little ones spend around 200 days as a fetus before they are released into the wild. Upon birth, they weight 4.67 kg (10.3 lbs) and measure 4 cm (0′ 2″). They are a member of the Cercopithecidae family (genus: Rhinopithecus). An adult Tonkin snub-nosed monkey grows up to a size of 56.9 cm (1′ 11″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
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”.
