Often called the finger monkey, these tiny monkeys grow the size of a barbie doll and weigh less than a pound as adults. Don't let their adorable size and facial expressions fool you, they are very curious and highly intelligent. Because they are new world primates, they are the most difficult animals we raise, they require the most dedication and time, all the time. These monkeys have special requirements, not like other animals, including special lighting, diet, veterinary expertise, neutering, and more. They are highly specialized and are not easy to care for.  If you are seriously interested in obtaining a marmoset monkey please read my Buy a Marmoset Monkey Guide and sign up for our notification list at the bottom of this page.
