What me worry? Spider Monkey hangs by tail.

I took this picture when I was on vacation in Costa Rica. The monkey

is fairly high in the tree and it's using its prehensile tail to keep

from falling. This picture is cropped from a larger picture so it

isn't quite as clear as I'd like. If I had a rapid fire camera, I

could try to get a picture with its hand slightly moved to show its

face. It may be underexposed.
