Overview
Corals reefs are formed over a process of thousands of years. Each coral reef is made up of colonies of tiny animals called polyps. Each polyp produces calcium carbonate, which makes up their skeleton and protects corals internal bodies; similar to how our skeleton protects our organs. Polyps on their own are colorless, however, each polyp attracts large amounts of algae, called zooxanthellae. These algae live inside the cells of the polyp and gives corals their vibrant colors.
Corals, and the algae inside their polyps, rely on sunlight to produce the energy needed for them to survive and grow. That’s why most coral reefs can be found in shallow, clear water along the coast. Corals crave the marine conditions found in the warm waters of the tropics and sub-tropics.
Benefits of Coral Reefs
Coral reefs are vital for a healthy ecosystem!
- Habitat: They support 25% of all marine animals, from thousands of fish species to sponges to marine mammals.
- Protection from storms: Coral reefs are also our first line of defense against tropical storms, helping to protect all of our coastal communities.
