These are: Major regions of coral reef development. (1) The Indo-Pacific-Includes most of the Indian Ocean (excluding the Red Sea), and the western Pacific. (2) The Wider Caribbean (tropical western Atlantic) - Includes Florida, The Bahamas, Caribbean Sea proper, and coastal waters off northeastern S. America.
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.
