Over on Yahoo's most emailed photos they have several images of these tiny Pygmy Marmoset monkeys which have been kicking around in the top 25 or so for the last two weeks. The photos of these monkeys are from a zoo in Sweden but over on YouTube there is a video of the tiny monkeys in action at a zoo in Canada. According to the caption for this photo these tiny monkey's are the smallest monkeys in the world and live in the upper Amazon basin. The video of the Pygmy Marmoset monkeys shows an adult size monkey next to a baby and then has a hand that moves into camera range for a size comparison.
Check out the video of the pygmy marmoset monkey below or on the host site. And check out the full sized photos of the minature monkeys over on Yahoo.
