Could You Spot These 7 Color-Changing Animals? (VIDEO)

Remember the big "Magic Eye" craze a decade or so ago? Here's something way cooler -- a bunch of animals that blend into nature, some of which require a little eye-crossing to find. From WebEcoist:

The flounder at first appears as rather ungainly-looking bottom-feeding flat fish, but has the amazing ability to adapt their appearance to their environment in search of prey along the ocean floor. To further aid their stealth, their second eye actually migrates to one side of their body (left or right depending on the species) as they get older. This enables them to cruise along parallel to the ground below them (essentially on their side) and still look up and forward. Further, these industrious creatures have even (surprisingly) been found at the bottom of deepest location on the Earth's crust - the Mariana Trench - at depths of 35,000 feet.
