We all know that corals come in just about every color under the sun. Red, blue, green, brown, even black - you can get corals in nearly any color. But why are they the colors they are? Why would an animal go through all that trouble just to look pretty?

It turns out the colors we see are actually important protection from the sun. The proteins that make up the colors fluoresce under sunlight and reflect in all the bright colors we expect. Other proteins don't fluoresce but look great at other times under whiter light.
