It is hard to guess what a Sun-tailed monkey weights. But we have the answer:
An adult Sun-tailed monkey (Cercopithecus solatus) on average weights 5.26 kg (11.59 lbs).
The Sun-tailed monkey is from the family Cercopithecidae (genus: Cercopithecus). When reaching adult age, they grow up to 54.5 cm (1′ 10″). Usually, Sun-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 sun-tailed monkey (Allochrocebus solatus) from Gabon is one of the least studied primates in its habitat. It was discovered as a new species in 1988, and is classified as a guenon, which is a member of the genus Cercopithecus, but was subsequently moved to the genus Allochrocebus. It is closely related to A. preussi and A. Ihoesti, which has been determined by chromosomal analysis. Sun-tailed monkeys prefer shady areas with dense vegetation. However, even after small amounts of logging activity, populations can be unaffected. Much of their diet remains unknown and is still being studied, but they are known to prefer fruit. Their social groups are made up of one male and multiple females. Generally, the sun-tailed monkey is less aggressive towards related individuals, which is noteworthy because it has been found that, in other primate species, aggression rates towards related individuals are generally as high or higher than aggression rates towards non-related individuals. Within their social groups, individual monkeys show preference for their mothers over their fathers, and are overall less aggressive to other monkeys that they are associated with spatially.
