Photographer Art Wolfe has spent decades capturing not just the hidden world of animals, but also the world of hidden animals. In his Vanishing Act series of photos, he invites us to search his images for the camouflaged animals within. For example, do you see the mantis in that top picture? Wolfe has a huge collection of these images—along with their solutions—at his blog, or you can purchase his Vanishing Act book.
