Samoana Attenuata
''Samoana attenuata'' is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species is endemic to French Polynesia. Conservation The slender snail was widespread in Society Islands. But in the late 1980s, carnivorous ''Euglandina rosea'' was introduced into Society Islands and ''Samoana attenuata'' snails disappearing quickly. Populations on Raiatea thought to be extinct until 2006. now, the species is living on Raiatea, Tahiti, and Moorea. Unfortunately, the species is extinct on Bora Bora Bora Bora ( French: ''Bora-Bora''; Tahitian: ''Pora Pora'') is an island group in the Leeward Islands.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Bora Bora
Bora Bora ( French: ''Bora-Bora''; Tahitian: ''Pora Pora'') is an island group in the Leeward Islands. The Leeward Islands comprise the western part of the Society Islands of French Polynesia, which is an overseas collectivity of the French Republic in the Pacific Ocean. Bora Bora has a total land area of . The main island, located about northwest of Papeete, is surrounded by a lagoon and a barrier reef. In the center of the island are the remnants of an extinct volcano, rising to two peaks, Mount Pahia and Mount Otemanu; the highest point is at . Bora Bora is part of the Commune of Bora-Bora, which also includes the atoll of Tūpai. The languages spoken in Bora Bora are Tahitian and French. However, due to the high tourism population, many natives of Bora Bora have learned to speak English. Bora Bora is a major international tourist destination, famous for its seaside (and even offshore) luxury resorts. The major settlement, Vaitape, is on the western side of the mai ...

Raiatea
Raiatea or Ra'iatea ( Tahitian: ''Ra‘iātea'') is the second largest of the Society Islands, after Tahiti, in French Polynesia. The island is widely regarded as the "centre" of the eastern islands in ancient Polynesia and it is likely that the organised migrations to the Hawaiian Islands, New Zealand and other parts of East Polynesia started at Raiatea. A traditional name for the island is Havai'i, homeland of the Māori people. Situated on the southeast coast is the historical Taputapuatea marae, which was established by 1000 CE. The site was the political and religious center of eastern Polynesia for several centuries, and was inscribed on the UNESCO World Heritage List in 2017 for its historical significance. The main township on Raiatea is Uturoa, the administrative centre for the Leeward Islands (French ''Îles Sous-le-vent''). There are also colleges which serve as the main educational location for secondary schools for students from the regional islands of Bora Bor ...

Society Islands
The Society Islands (french: Îles de la Société, officially ''Archipel de la Société;'' ty, Tōtaiete mā) are an archipelago located in the South Pacific Ocean. Politically, they are part of French Polynesia, an overseas country of the French Republic. Geographically, they form part of 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 wrote in his journal that he called the islands ''Society'' "as they lay contiguous to one another." History Dating colonization The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in term of a orally transmitted story. The feathered god Ta'aroa lay in his shell. He called out but no-one answered, so he went back into his shell, where he stayed for aeons. When he ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.
