Information: - The Acteon Group ( Groupe Acteon ) is a rather isolated and uninhabited subgroup in the far southeast of the Tuamotu atoll group in French Polynesia . It is located about 1,400 km ( 870 mi ) east - southeast of Tahiti at latitude : 21 17 ' 60 S , longitude : 136 29 ' W. - An atoll (, , , or ), sometimes called a coral atoll, is a ring-shaped coral reef including a coral rim that encircles a lagoon partially or completely. There may be coral islands/cays on the rim. - The French overseas collectivities (or "COM"), like the French regions, are first-order administrative divisions of France. The COMs include some former French overseas territories and other French overseas entities with a particular status, all of which became COMs by constitutional reform on 28 March 2003. The COMs should not be confused with the overseas regions and overseas departments which have no particular status. As integral parts of France, overseas collectivities are represented in the National Assembly, Senate and Economic and Social Council. Only one COM, Saint Martin, is part of the European Union and can vote to elect members of the European Parliament (MEP). The Pacific COMs use the CFP franc, a currency pegged to the euro, whereas the Atlantic COMs use the euro directly. As of 31 March 2011, there were five COMs: - A cay (or ), also spelled caye or key, is a small, low-elevation, sandy island on the surface of a coral reef. Cays occur in tropical environments throughout the Pacific, Atlantic and Indian Oceans (including in the Caribbean and on the Great Barrier Reef and Belize Barrier Reef). - A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. - Tahiti is the largest island in the Windward group of French Polynesia; this overseas collectivity of the French Republic is sometimes referred to as an overseas country. The island is located in the archipelago of the Society Islands in the central Southern Pacific Ocean, and is divided into two parts: The bigger, northwestern part "Tahiti Nui" and the smaller, southeastern part "Tahiti Iti". The island was formed from volcanic activity and is high and mountainous with surrounding coral reefs. The population is 183,645 inhabitants (2012 census), making it the most populous island of French Polynesia and accounting for 68.5 percent of its total population. - 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. - The Society Islands includes a group of islands in the South Pacific Ocean. It is, politically and legally, part of French Polynesia. The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769, supposedly in honour of the Royal Society, the sponsor of the first British scientific survey of the islands; however, Cook, himself, stated in his journal that he called the islands "Society" "as they lay contiguous to one another." - Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Most reefs grow best in warm, shallow, clear, sunny and agitated waters. - Polynesia ( from "poly" "many" + "nsos" "island") is a subregion of Oceania, made up of over 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are termed Polynesians and they share many similar traits including language family, culture, and beliefs. Historically, they were experienced sailors and used stars to navigate during the night. - French Polynesia is an overseas collectivity of the French Republic; " (COM)", sometimes unofficially referred to as an overseas country; " (POM)". It is composed of 118 geographically dispersed islands and atolls stretching over an expanse of more than in the South Pacific Ocean. Its total land area is . - An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word "archipelago" is derived from the Greek "- arkhi-" ("chief") and " pelagos" ("sea") through the Italian "arcipelago". In Italian, possibly following a tradition of antiquity, the Archipelago (from medieval Greek "*" and Latin "archipelagus") was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to refer to any island group or, sometimes, to a sea containing a small number of scattered islands. - The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east. - Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
