Coral reefs are made up of tiny animals that called “polyps” that stay fixed in one place and are the main structure of a reef. Polyps have a hard outer skeleton made of calcium (similar to a snails shell). Polyp is connected by living tissue that forms a community. Coral reefs may vary in size, type, and location around the world but are very sensitive to water properties like temperature, and chemical composition. The top layer is of a coral reef contains living polyp. When new layers of the coral reef are built, the polyps then the leave the lower layers. Each polyp has a ring of tentacles shaped like a cup around a central opening. The tentacles have stinging cells, called nematocysts, which allow the coral polyp to capture small organisms that swim too close. Nearly half or I’d rather say all of the worlds coral reefs, are in the tropics. How beautiful does that sound? Coral reefs are also important to us (humans).

    The presence of coral reefs acts as a buffer to protect and preserve shorelines from tidal damage and storm surges. Additionally, reefs provide spawning, nursery, refuge and feeding areas for a large variety of organisms. Their presence alone can yield an average of fifteen tons of fish and other seafood per square kilometer annually (Fast Facts). Moreover, reefs generate billions of dollars in tourism and represent a staple food source for many people across the globe. Based upon scientific trends and the ecological dependency many marine species have on coral reefs, several countries established marine sanctuaries in order to aid in conservation efforts.…
