How much does a Purple-faced langur weight?

It is hard to guess what a Purple-faced langur weights. But we have the answer:

An adult Purple-faced langur (Trachypithecus vetulus) on average weights 7.53 kg (16.61 lbs).

The Purple-faced langur is from the family Cercopithecidae (genus: Trachypithecus). It is usually born with about 360 grams (0.79 lbs). They can live for up to 23 years. When reaching adult age, they grow up to 58.5 cm (2′ 0″). Usually, Purple-faced langurs 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 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).
