A coral reef is made of thin layers of calcium carbonate. Coral polyps form a living mat over a calcium carbonate skeleton. Stony corals (or scleractinians) are the corals primarily responsible for laying the foundations of, and building up, reef structures.
Cuttlefish (Sepiida) are in an Order of mollusks that possess an internal shell called the cuttlebone. The cuttlebone is made of calcium carbonate and plays a dominant role in these mollusks' buoyancy; it is divided into tiny chambers in which the cuttlefish can fill or empty of gas, depending on its needs.
