1 In the blue underwater world, there are many creatures that are not what they appear to be. One of the best examples of this is corals.
2 Corals come in a variety of shapes, sizes, and colors. Some resemble trees with leafless branches. Some look like mushrooms. Some remind us of human brains. The list goes on and on. Regardless of what they appear to be, they are usually fixtures on rocks. Their lack of mobility is like vegetation on land -- plants grow, but they do not uproot themselves to go somewhere else. So, just as we are ready to classify corals as underwater plants, we realize that they are actually animals!
3 "Coral" can mean one of two things. The first is the living marine invertebrate itself that we also refer to as a coral polyp or a polyp. The second is the limestone skeleton some coral species have and leave behind when they die. We call them "hard corals"; for those without a limestone skeleton, we call them "soft corals." The calcareous remains of hard corals become the framework of coral reefs.
