Corals and their relatives. When people think of corals, usually the first thing they picture is not an actual coral, but a coral reef: large calcium carbonate (limestone) structures, filled with colorful plants and animals. Corals themselves are only one part of coral reefs (albeit a very important one) and while they secrete the material that makes up the reefs (calcium carbonate), they are, in fact, animals. Corals are relatives of jellyfish and anemones. While at first glance they may look nothing like their relatives, if you take a closer look you start to see some similarities.
