How many baby Sun-tailed monkeys are in a litter?
A Sun-tailed monkey (Cercopithecus solatus) usually gives birth to around 1 babies.
Upon birth, they weight 338 grams (0.75 lbs) and measure 2.9 cm (0′ 2″). They are a member of the Cercopithecidae family (genus: Cercopithecus). An adult Sun-tailed monkey grows up to a size of 54.5 cm (1′ 10″).
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 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.
