The coral reefs existing today began growing as early as 50 million years ago. Most established coral reefs are between 5,000 and 10,000 years old. Although size can be a good indicator of the age of a coral reef, it is not a certain indicator.he coral reefs existing today began growing as early as 50 million years ago.

LOCATION: Coral reefs are generally found in clear, tropical oceans. Coral reefs form in waters from the surface to about 150 feet (45 meters) deep because they need sunlight to survive.The three types of reefs include fringing reefs, barrier reefs, and atolls.eefs need calcium from the water to grow, which is more often available in shallow warm waters. PLANTS: The sun is the source of energy for the coral reef ecosystem. Plant plankton, called phytoplankton, algae and other plants convert light energy into chemical energy through photosynthesis.
