What is Coral?

Although Coral looks very much like colorful oceanic plant life, coral is actually an animal! Baby coral looks like little jelly fish floating in the water until it finds a hard place to attach to. Once it lands and attaches, it builds itself a shell of limestone. The shell is shaped like a round vase and the coral polyp lives inside. A coral reef is about a million of these animals, stuck one atop the other. There are over 500 species of coral.
