The World's Smallest Monkey

The smallest monkey in the world is pygmy marmoset (Cebuella pygmaea) which can be found in Brazil, Columbia, Ecuador, Bolivia and some places of Peru. This monkey grows to a height of 11 to 15 cm and has a 17-22 cm long tail. It weighs only 120 to 190 grams; and weighs only 15 grams at the time of birth.

Pygmy marmosets live 11-12 years in the wild, but in zoos, they live into their early twenties. Marmosets often live in groups made up of an adult pair and its offspring; ranging from 2-6 members. Young marmosets typically remain in the group until after 2 consecutive birth cycles.
