A coral island is a type of island formed from coral detritus and associated organic material. They occur in tropical and sub-tropical areas, typically as part of coral reefs which have grown to cover a far larger area under the sea.
Most of the world's coral islands are in the Pacific Ocean. The American territories of Jarvis, Baker and Howland Islands are clear examples of coral islands. Also, some of the islands belonging to Kiribati are considered coral islands. The Maldives also consist of coral islands.
Many coral islands are small and not high above sea level, so are at threat from cyclones, storms and rising sea levels.
