corals are primarily responsible for laying the foundations of, and building up, reef structures. They are made up of Meandrina also known as brain coral.Massive reef structures are formed when each individual stony coral organism—or polyp—secretes a skeleton of calcium carbonate.The corals have very small polyps,they are approx two or three millimeters (0.04 to 0.12 inches) in diameter, but entire colonies can grow very large and weigh several tons.
