How old are today’s reefs?

What is a coral? Colonial Animal mouth tentacle stomach

What do corals need to grow? Dr. James P. McVey, NOAA Sea Grant Program SunlightClear shallow water Warm water (above 68 degrees F) Room to settle and grow

How is a coral reef formed? Dr. James P. McVey, NOAA Sea Grant Program Each polyp builds a case of limestone around itself. This case remains after the polyp has died, and forms a foundation for another polyp to build on. Over time the coral colony forms the structures which make up a coral reef.
