Coral reefs are formed when free-swimming coral larvae get attached to a submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures —fringing, barrier or atoll. They are said to be diverse under water ecosystems. Most reefs grow best in warm, shallow, clear, sunny and agitated waters.
