Most structures that we call "coral" are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps.Coral atolls develop from reefs fringing volcanic islands. Reefs fringing volcanic islands build vertically to sea level, forming steep-walled barrier reefs. As a volcanic island subsides, or sinks, with time, the growing reef keeps pace with the rising water level. When the island eventually submerges, the ring-shaped reef forms an atoll with ...Along many reefs, coral spawning occurs as a synchronized event, when many coral species release their gametes around the same time. With all the corals on a reef releasing gametes at the same time, there’s a better chance of escaping hungry predators and a greater possibility that many different genetic combinations may form.A coral reef fishery as a multilevel social–ecological network.
