Marmoset Monkey is a type of monkey that has a gray or black body, a long tail, and a white head with black ears. They are medium in size and spend a great deal of their time in the trees. They have tuffs on their ears too so you may hear them called the tufted eared marmoset as well.
They are about 50 inches long. They consume sap, food, insects, and sometimes small mammals. They are opportunistic and will eat what they can find. They live in small social groups of about 8 members and they move around often looking for food and shelter.
