Geoffroy's marmosets are one of the most beautiful marmosets, with their multi-colored fur and white faces. They are from South America. Their diet consits primarily of fruits, bark, insects and small mammals. There are also quite a few marmoset diets available.

Marmosets can live up to 16 years in captivity, and are social animals. They usually live in small groups of 4 to 16 animals. One point of interest is that the males have as big a role in caring for the babies as the females.
