Each year, Nikon holds its Small World Photomicrography Competition, showcasing the wonders of a world we can only see through a microscope. These finalists' photos offer unusual views on everything from rain on a butterfly's wing to fossilized dinosaur bones.

The winners for the 2009 competition will be announced this Thursday, October 8th. In the meantime, you can play a few rounds of Identify the Image with more finalist photos on the competition website.
