This is Loango, a crown male Mangabey monkey, who was rejected by his mother shortly after birth. The baby was born in March 2012 at the Jardin des Plantes's zoo in Paris. He's being hand raised by zookeepers.
Here are some cute and adorable baby monkey pictures. All the old world monkeys are mainly found in India, Africa, Central to Southern Asia and Japan. But the new world monkeys are found in Mexico, Central and South America.
