It is hard to guess what a Red-tailed monkey weights. But we have the answer:
An adult Red-tailed monkey (Cercopithecus ascanius) on average weights 3.54 kg (7.8 lbs).
The Red-tailed monkey is from the family Cercopithecidae (genus: Cercopithecus). It is usually born with about 371 grams (0.82 lbs). They can live for up to 28.25 years. When reaching adult age, they grow up to 44.4 cm (1′ 6″). Usually, Red-tailed 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 red-tailed monkey, also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt’s guenon (Cercopithecus ascanius) is a species of primate in the family Cercopithecidae.It is found in Angola, Cameroon, Central African Republic, Democratic Republic of the Congo, Kenya, Rwanda, South Sudan, Tanzania, Uganda, Zambia, and possibly Burundi. The red-tailed monkey is usually black, red, or orange. Although native to this region, it has spread north and south as well as it can survive in different habitats and under different conditions. It is a distinct creature in its habitats and is gradually becoming endangered due to deforestation and over-exploitation through hunting and predation.
