Marmosets are quick, agile jumpers.
Some can leap up to 4m, powered by hind legs which are longer than the front limbs. Its tail, which is a lot longer than its body, is used for balance as it bounces off branches. The tail is not prehensile. It has keen eyesight and hearing and a good sense of smell. Marmosets are active in the daytime, although they tend to snooze during the hottest part of the day.
