There are four different types of spider monkey, all of which are fairly large in size and get to around 50cm tall, plus the spider monkey's tail which can often grow longer than the spider monkey's body.
Due to the extensive hunting of the spider monkey from both humans and bigger jungle animals such as the jaguar and the crocodile, all four species of spider monkey are now considered to be endangered or critically endangered.
The spider monkey is often kept as an exotic pet worldwide and is one of the most popular species of pet monkey due to the spider monkey's looks and the spider monkey's character. Please don't keep spider monkeys as pets. Spider monkeys belong in the jungles were they come from and are on the verge of extinction, this process should not be helped.
Spider monkeys form groups of between 10 and 30 individuals which splits up during the day so that there is less competition for food. Unlike many other primates, it is the female spider monkeys that leave their original group to join new groups, rather than the male spider monkeys. Male spider monkeys are known to stay together throughout their lives.
Female spider monkeys breed every three to four years and when she is ready to, the female spider monkey chooses a male spider monkey from her group in which to mate with. After a gestation period of around 7 months, the female spider monkey will give birth to one baby spider monkey.
Baby spider monkeys completely rely on their mother until they are between 6 to 10 months old and are big enough and strong enough to make it on their own. Until then, the mother spider monkey carries her young on her tummy and then on her back in on order to keep them safe. Female spider monkeys are known to help their young when jumping in the trees and groom them too.
