The pygmy marmoset is the smallest monkey in the world, and is about the size of a small squirrel and weighs about as much as a Quarter Pounder, bun and all.
In fact, marmosets clamber up trees like squirrels, they’re one of the few monkeys that have claws instead of fingers and toenails.
While up in the trees, they feast on insects and fruit, and chew holes in trees to suck out the sap.
The Pygmy Marmoset also known as the Dwarf Monkey is a New World monkey not much larger than 6 inches when fully grown, and can be found in the rain forests of Brazil, Colombia, eastern Ecuador, Peru, and northern Bolivia.
