How many baby Geoffroy’s spider monkeys are in a litter?
A Geoffroy’s spider monkey (Ateles geoffroyi) usually gives birth to around 1 babies.
Each of those little ones spend around 226 days as a fetus before they are released into the wild. Upon birth, they weight 425 grams (0.94 lbs) and measure 5.8 cm (0′ 3″). They are a member of the Cebidae family (genus: Ateles). An adult Geoffroy’s spider monkey grows up to a size of 43.3 cm (1′ 6″).
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.
Geoffroy’s spider monkey (Ateles geoffroyi), also known as the black-handed spider monkey, is a species of spider monkey, a type of New World monkey, from Central America, parts of Mexico and possibly a small portion of Colombia. There are at least five subspecies. Some primatologists classify the black-headed spider monkey (A. fusciceps), found in Panama, Colombia, and Ecuador as the same species as Geoffroy’s spider monkey.It is one of the largest New World monkeys, often weighing as much as 9 kg (20 lb). Its arms are significantly longer than its legs, and its prehensile tail can support the entire weight of the monkey and is used as an extra limb. Its hands have only a vestigial thumb, but long, strong, hook-like fingers. These adaptations allow the monkey to move by swinging by its arms beneath the tree branches.Geoffroy’s spider monkey lives in fission–fusion societies that contain between 20 and 42 members. Its diet consists primarily of ripe fruit and it requires large tracts of forest to survive. As a result of habitat loss, hunting and capture for the pet trade, it is considered to be endangered by the IUCN.
