How many baby Purple-faced langurs are in a litter?
A Purple-faced langur (Trachypithecus vetulus) usually gives birth to around 1 babies.
Each of those little ones spend around 204 days as a fetus before they are released into the wild. Upon birth, they weight 360 grams (0.79 lbs) and measure 36.8 cm (1′ 3″). They are a member of the Cercopithecidae family (genus: Trachypithecus). An adult Purple-faced langur grows up to a size of 58.5 cm (2′ 0″).
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 purple-faced langur (Semnopithecus vetulus), also known as the purple-faced leaf monkey, is a species of Old World monkey that is endemic to Sri Lanka. The animal is a long-tailed arboreal species, identified by a mostly brown appearance, dark face (with paler lower face) and a very shy nature. The species was once highly prevalent, found in suburban Colombo and the “wet zone” villages (areas with high temperatures and high humidity throughout the year, whilst rain deluges occur during the monsoon seasons), but rapid urbanization has led to a significant decrease in the population level of the monkeys. It had traditionally been classified within the lutung genus Trachypithecus but was moved to the genus Semnopithecus based on DNA evidence indicating that is it more closely related to the gray langurs.In Sinhala it is known as ශ්රී ලංකා කලු වදුරා (Sri Lanka black monkey).
