Now you see them, now you don't. After showing you photographer Graham McGeorge's incredible photos of owls camouflaged within trees, we decided to scour the web to look for more animals that are masters of disguise. Which animals famously blend into their environment? Who are the chameleons, changing their colors to match their backgrounds? We've rounded up stunning photos of these hidden animals. Sometimes they're so invisible, in fact, that even from your computer you may not be able to spot them!
