The Miami Terrace Reef (25°45′N79°55′W) is a coral reef off the coast of Florida stretching from South Miami to Boca Raton, in the Atlantic Ocean. It lies in depths of 650 to 2,000 feet (200 to 600 meters) on top of a geological formation known as the Miami Terrace, a 65 km long shelf about 15 miles off shore. Much of the platform remains unexplored, and new portions of the reef are still being discovered.
