The spider monkey that is generally found in the tropical rainforests of South and Central America, and also southern Brazil and Mexico is a popular monkey for many to opt for as a pet. Unfortunately, these impressive creatures are not very easy to attain and you will need to cut through quite a lot of red tape before you can actually obtain your dream pet. There are a number of websites on the Internet that you can purchase spider monkeys from and a number of other monkey varieties.
The rare and endangered black-headed spider monkey is one that you will not be able to purchase. Whether or not you can actually purchase these creatures though will actually depend on where you reside. There are a number of different states in America that simply do not allow you to own these monkeys and many of the states that do allow you to, will force you to have the animal bonded for an extremely large figure (usually around $40,000).
This is a similar case in many parts of the world, to be brutally honest these wild animals are not the ideal pets, they should really be left in their natural habitat as this is where they are happiest, but if you really want one it is possible.
