By: Aysa Zebekow

Finger monkeys, also known as pygmy marmosets, are the world's smallest monkey species, measuring just 5-6 inches long and weighing about 3-5 ounces. These tiny primates live in the Amazon rainforests of South America, where they face threats from habitat loss and the illegal pet trade, leading to their classification as a vulnerable species.
