Information: - A polyp in zoology is one of two forms found in the phylum Cnidaria, the other being the medusa. Polyps are approximately cylindrical in shape and elongated at the axis of the vase-shaped body. In solitary polyps, the aboral end is attached to the substrate by means of a disc-like holdfast called the pedal disc, while in colonies of polyps it is connected to other polyps, either directly or indirectly. The oral end contains the mouth, and is surrounded by a circlet of tentacles. - Calcium carbonate is a chemical compound with the formula CaCO. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which contains both of those minerals) and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous. - 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 Marshall Islands, officially the Republic of the Marshall Islands, is an island country located near the equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 53,158 people (at the 2011 Census) is spread out over 29 coral atolls, comprising 1,156 individual islands and islets. The islands share maritime boundaries with the Federated States of Micronesia to the west, Wake Island to the north, Kiribati to the south-east, and Nauru to the south. About 27,797 of the islanders (at the 2011 Census) live on Majuro, which contains the capital. - 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 . - 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. - Cnidaria is a phylum containing over 10,000 species of animals found exclusively in aquatic (freshwater and marine) environments: they are predominantly marine species. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. They have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyphozoa possess balance-sensing statocysts, and some have simple eyes. Not all cnidarians reproduce sexually, with many species having complex life cycles of asexual polyp stages and sexual medusae. Some, however, omit either the polyp or the medusa stage. - In biology, a phylum (plural: phyla) is a taxonomic rank below kingdom and above class. Traditionally, in botany the term division was used instead of "phylum", although from 1993 the International Code of Nomenclature for algae, fungi, and plants accepted the designation "phylum". Depending on definitions, the kingdom Animalia contains approximately 35 phyla, Plantae contains about 12, and Fungi contains around 7. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta. - The Tuamotus or the Tuamotu Archipelago (officially "") are a French Polynesian chain of almost 80 islands and atolls, stretching from the northwest to the southeast over an area of the southern Pacific Ocean roughly the size of Western Europe, with a land area of and 16,000 inhabitants, forming the largest chain of atolls in the world. Its major islands are Anaa, Fakarava, Hao and Makemo. - 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. - 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." - Mataiva ( meaning '' Nine Eyes '' in Tuamotuan ) , Tepoetiriura ( '' Sparkling Pearl '' ) or Lazarev atoll is a coral atoll in the Tuamotu Archipelago . It is located in the Palliser group , and is the westernmost of the Tuamotus . The nearest atoll , Tikehau , is located 35 km to the east . Rangiroa is located 79 km to the east , and Tahiti is 311 km to the south . - 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). - 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: - 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. - 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. - Marine invertebrates are the invertebrates that live in marine habitats. Invertebrate is a blanket term that includes all animals apart from the vertebrate members of the chordate phylum. Invertebrates lack a vertebral column, and some have evolved a shell or a hard exoskeleton. As on land and in the air, marine invertebrates have a large variety of body plans, and have been categorised into over 30 phyla. They make up most of the macroscopic life in the oceans. - An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land. - Anthozoa is a class within the phylum Cnidaria. Unlike other cnidarians, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows. Some anthozoans can also reproduce asexually through budding. More than 6,100 species have been described. - The Palliser Islands or Pallisers are a subgroup of the Tuamotu group in French Polynesia. They are located in the very northwest of the main group of atolls. - Rangiroa (meaning "Vast Sky" in Tuamotuan) or Te Kokta ("Hyades" in Mori), is the largest atoll in the Tuamotus, and one of the largest in the world (although it is smaller than Kwajalein in the Marshall Islands and Huvadhu in the Maldives). It is part of the Palliser group. The nearest atoll is Tikehau, located only 12km to the west. It is about 355km northeast of Tahiti. - 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. - 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. - 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 Maldives (, or ), officially the Republic of Maldives (""), is a South Asian island country, located in the Indian Ocean. It lies southwest of India and Sri Lanka. The chain of twenty-six atolls stretches from Ihavandhippolhu Atoll in the north to the Addu City in the south. Comprising a territory spanning roughly , the Maldives is one of the world's most geographically dispersed countries, as well as the smallest Asian country by both land area and population, with a little over 393,500 inhabitants. Male is the capital and most populated city, traditionally called the "King's Island" for its central location. - Calcium is a chemical element with symbolCa and atomic number20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis. - Tikehau (meaning "Peaceful Landing" in Tuamotuan) or Porutu-kai is a coral atoll in the Palliser Islands group, part of the Tuamotu Archipelago in French Polynesia. It is included in the commune of Rangiroa. 'mataiva' is related to which object entity through the relation of 'part of'?
