Nerite
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. MolluscaBase eds. (2021). MolluscaBase. Neritininae Poey, 1852. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=411639 on 2021-09-25 The family Neritidae includes marine genera such as ''Nerita'', marine and freshwater genera such as ''Neritina'', and freshwater and brackish water genera such as ''Theodoxus''. The common name "nerite" as well as the family name Neritidae and the genus name ''Nerita'', are derived from the name of Nerites, who was a sea god in Greek mythology. Distribution Neritidae live primarily in the southern hemisphere, but there are some exceptions, such as a genus ''Theodoxus'' which can be found in Europe and Northern Africa Bunje P.

Theodoxus Fluviatilis
''Theodoxus fluviatilis'', common name the river nerite, is a species of small freshwater and brackish water snail with a gill and an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites.Neubauer, Thomas A. (2014). ''Theodoxus'' (''Theodoxus'') ''fluviatilis'' (Linnaeus, 1758). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=821986 on 2014-11-18 This widely distributed neritid snail species occurs from Europe to Central Asia.

Theodoxus
''Theodoxus'' is a genus of nerites, small water snails with an operculum, some of which live in freshwater, and some in both freshwater and brackish water, aquatic gastropod mollusks in the family Neritidae, the nerites.Bouchet, P. (2014). Theodoxus Montfort, 1810. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=153531 on 2014-11-17. Distribution The distribution of the genus ''Theodoxus'' includes Europe and northern Africa and also extends east to southern Iran. No other species within Neritidae have sympatrical distribution with ''Theodoxus''. The distribution of the genus ''Theodoxus'' is an exception within Neritidae, because Neritidae live primarily in the southern hemisphere. Species within ''Theodoxus'' are the only Neritidae snails, that live in temperate climate. Bunje & Lindberg (2007) presented the first phylogenetic hypothesis of the clade ''Theodoxus''.Bunje P.

Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Bathynerita Naticoidea
''Bathynerita naticoidea'' is a species of small sea snail, a marine gastropod mollusc in the family Neritidae, the nerites. This species is endemic to underwater cold seeps (oil seeps and gas seeps) in the northern Gulf of Mexico and in the Caribbean. The possible placement of this species within the closely allied family Phenacolepadidae has been under discussion. Species from these habitats can be collected by manned submersibles or by remotely operated underwater vehicles. Distribution This species lives in cold seeps in the northern Gulf of Mexico and in the accretionary wedge of Barbados in the Caribbean in the upper continental slope, in depths from 400 to 2100 m.

Nerites (mythology)
In Greek mythology, Nerites ( el, Νηρίτης, Nērítēs) was a minor sea deity, the son of "Old Man of the Sea" Nereus and the Oceanid Doris and brother of the fifty Nereids (apparently their only male sibling). He was described as a young boy of stunning beauty. According to Aelian, Nerites was never mentioned by epic poets such as Homer and Hesiod, but was a common figure in the mariners' folklore. Aelian, ''De Natura Animalium'14.28 Etymology According to Aristoteles, the name '' nerites'' refers to many species of sea snails. R. S. P. Beekes suggests a Pre-Greek origin for the word. Mythology Aelian cites two versions of the myth concerning Nerites, which are as follows: In one of the versions, Aphrodite, before her ascension from the sea to Olympus, fell in love with Nerites. When the time had come for her to join the Olympian gods, she wanted Nerites to go with her, but he refused, preferring to stay with his family in the sea. Even the fact that Aphrodite pr ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Arthur William Baden Powell
Arthur William Baden Powell (4 April 1901 – 1 July 1987) was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden". Biography Early life The name Baden had been a given name in a Powell family since 1731, when Susannah Powell née Thistlethwayte (1696–1762) gave to her child (1731–1792) the maiden name of her mother, Susannah Baden (1663–1692). The name Baden, particularly when associated with the surname Powell, became famous in 1900–1901, the year Arthur William Baden Powell was born, because of the siege of Mafeking, the most famous British action in the Second Boer War, which turned the British commander of the besieged, Robert Baden-Powell, into a national hero. Throughout the British Empire, babies were named after him. No family connection has yet been established between Arthur W ...
