What are coral islands?
Coral polyps are tiny marine animals which live in mud-free shallow and warm waters. They secrete calcium carbonate. The secretion of calcium carbonate results in the formation of coral reefs. Islands formed of such coral reefs are known as coral islands.
Coral islands, also known as coral atolls, are a type of island formed primarily by the accumulation of coral reef deposits. They are typically found in tropical or subtropical regions with clear and shallow waters. Coral reefs are composed of the calcium carbonate skeletons secreted by tiny marine animals called coral polyps. One of the popular island is Pattaya Coral Island.
