It is hard to guess what a Nilgiri langur weights. But we have the answer:
An adult Nilgiri langur (Trachypithecus johnii) on average weights 10.6 kg (23.36 lbs).
The Nilgiri langur is from the family Cercopithecidae (genus: Trachypithecus). When reaching adult age, they grow up to 55.3 cm (1′ 10″). Usually, Nilgiri 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 Nilgiri langur (Semnopithecus johnii) is a langur (a type of Old World monkey) found in the Nilgiri Hills of the Western Ghats in South India. Its range also includes Kodagu in Karnataka, Kodayar Hills in Tamil Nadu, and many other hilly areas in Kerala and Tamil Nadu. This primate has glossy black fur on its body and golden brown fur on its head. It is similar in size and long-tailed like the gray langurs. Females have a white patch of fur on the inner thigh. It typically lives in troops of nine to ten monkeys. Its diet consists of fruits, shoots and leaves. The species is classified as vulnerable due to habitat destruction and poaching for its fur and flesh, the latter believed to have aphrodisiac properties.
