Pygmy Marmoset Hugging a Banana

When I was a kid we had a big fat copy of the Guiness Book of World Records book and I remember constantly flipping to the page with the photo of the World's Smallest Monkey. It still makes me happy to look at this little guy!

Pygmy Marmosets live in South America and they grow to be 5 to 6 inches (not including their tails). You can read more about them at Wikipedia.
