Scientific Name: Callithrix geoffroyi
Geoffroy’s Marmosets are about 8 inches in length with a tail of about 11 inches.
Marmosets are among the only monkeys that regularly give birth to twins.
They are social animals and live in groups called troops led by a dominant female and male.
They are monogamous. Only the dominant female in the group will give birth. The entire troop including the males will help raise the offspring.
