Animals use coloration to improve their survival chances through concealment. Here's a fantastic little video with some amazing examples of nature at work.
Some animals simply look like an object to blend into it's surroundings. I guess I need to work on my shape if I want to truly blend in with the toned women in my exercise class... :-)
It's used by prey, and the predators. Some blend into the background, while others use bold blocks of color to break up the visual "bulk" of their form. Other times, conspicuous colors actually aid concealment, termed, "dazzle coloration". A zebra's stripes can confuse a predator who becomes unsure of it's speed and direction as it runs away.images source
