Corals captured in New Caledonia. Corals are fascinating colonial organisms found in the taxonomic class Anthozoa. When you look at a piece of coral, you’re actually observing hundreds or thousands of tiny individual organisms known as “polyps.” These polyps come in a variety of shapes, sizes, and colors. Researchers divide corals into two main groups: hard corals and soft corals.
