Taxonomy Of The Gastropoda (Bouchet Et Al., 2017)
The taxonomy of the Gastropoda as it was revised in December 2017 by Philippe Bouchet and eight other authors, is a publication which lays out a newly revised system for the scientific biological classification, classification of Gastropoda, gastropod mollusks. The same work also included the Monoplacophora#Taxonomy, taxonomy of monoplacophorans. The publication is entitled, "Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families"; it was published by the journal ''Malacologia''. Summary of the taxonomy The following cladogram shows a summary of the new gastropod taxonomy, according to the work's Contents section: †Paleozoic molluscs of uncertain position within Gastropoda or Monoplacophora (Unassigned to Superfamily) * †Family Khairkhaniidae Missarzhevsky, 1989 * †Family Ladamarekiidae Frýda, 1998 * †Family Metoptomatidae Wenz, 1938 * †Family Protoconchoididae Geyer, 1994 (=Patelliconidae Fryda, 1998) †Superfamily Archinacelloi ...

Philippe Bouchet
Philippe Bouchet (born 1953) is a French biologist whose primary scientific fields of study are malacology (the study of molluscs) and taxonomy. He works at the Muséum National d'Histoire Naturelle in Paris. He is also a Commissioner of the International Commission on Zoological Nomenclature. Bouchet published Taxonomy of the Gastropoda with the malacologist Jean-Pierre Rocroi in 2005, which laid out a new taxonomy of Gastropod molluscs. He has named over 500 new taxa of mollusks, and numerous taxa have been named in his honor. Professional achievements Bouchet is a senior professor at the Muséum National d'Histoire Naturelle in Paris, and is head of the Malacology laboratory and the Taxonomy Collections Unit there. He is also one of the Commissioners of the International Commission on Zoological Nomenclature and has been a member of the ICZN since 1990. Philippe Bouchet is co-editor of several volumes in the Tropical Deep-Sea Benthos series. In 2005, Bouchet was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vetigastropoda
Vetigastropoda is a major taxonomic group of sea snails, marine gastropod mollusks that form a very ancient lineage. Taxonomically the Vetigastropoda are sometimes treated as an order, although they are treated as an unranked clade in Bouchet and Rocroi, 2005. Vetigastropods are considered to be among the most primitive living gastropods, and are widely distributed in all oceans of the world. Their habitats range from the deep sea to intertidal zones. Many have shells with slits or other secondary openings. One of their main characteristics is the presence of intersected crossed platy shell structure. Most vetigastropods have some bilateral asymmetry of their organ systems. Description Vetigastropods range in size from approximately 0.08 in (2 mm) long in the case of Scissurelloidea or Skeneoidea, to more than 11.8 in (300 mm) in length, as with the Haliotoidea. External colours and patterns are typically drab, but such groups as the Tricolioidea and some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cerithiimorpha
The Cerithiimorpha was a suborder of marine gastropods within the Sorbeoconcha. This taxon is no longer valid according to the current taxonomy of Bouchet and Rocroi. The previous classification system was as follows: * subclassis = Orthogastropoda * infraclassis = Apogastropoda * superordo = Caenogastropoda * ordo = Sorbeoconcha * subordo = Cerithiimorpha Previous taxonomy During the taxon's use, not all taxonomists agreed upon its structure. The listing below gives one interpretation. For example, in another accepted classification, the Campaniloidea and Cerithioidea were separated in a suborder named Discopoda. * Campaniloidea ** Campanilidae ** Plesiotrochidae * Cerithioidea ** Batillariidae ** Brachytremidae ** † Canterburyellidae ** Cassiopidae ** Cerithiidae ** Dialidae ** Diastomidae ** Eoptychiidae ** Eustomidae ** Faxiidae ** Lavigeriidae ** Litiopidae ** †Maoraxidae ** Melanopsidae ** Modulidae ** Pachychilidae ** Pachymelaniidae ** Pareorida ...

The taxon Sorbeoconcha was named by Winston Ponder and David R. Lindberg in 1997. Taxonomy 1997 taxonomy According to the older taxonomy by Ponder and Lindberg the suborders within the order Sorbeoconcha are: * Discopoda P.

Architaenioglossa
Architaenioglossa is a taxonomic group of snails which have gills and often an operculum. They are primarily land and freshwater gastropod mollusks within the clade Caenogastropoda.

Caenogastropoda
Caenogastropoda is a taxonomic clade, a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The clade is the most diverse and ecologically successful of the gastropods. Caenogastropoda contains many families of shelled marine molluscs – including the periwinkles, cowries, wentletraps, moon snails, murexes, cone snails and turrids – and constitutes about 60% of all living gastropods. Biology The Caenogastropoda exhibit torsion, and thus are included in what was previously called the Streptoneura (meaning ''twisted nerves''), also known as Prosobranchia (meaning ''gills forward''). Specifically, they are characterized by having only a single auricle in the heart and a single pair of gill leaflets, and are equivalent to the Monotocardia or Pectinobranchia of older authors. Taxonomy The taxon Caenogastropoda was first established by Leslie Reginald Cox in 1960 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycloneritida
Cycloneritida (nerites and false-limpets) is an order of land snails, freshwater snails, and sea snails.MolluscaBase eds. (2020). MolluscaBase. Cycloneritida. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1054475 on 2020-08-21 These are gastropod molluscs within the subclass Neritimorpha. 14 of the families in the order are extant, and eight of the families are extinct. It was previously categorized as the clade Cycloneritimorpha. According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), as well as the Cycloneritida, the subclass Neritimorpha also contains the (entirely fossil) clade Cyrtoneritimorpha, plus a number of other fossil families that are currently unassigned. The earliest evolutionary forms of Cycloneritimorpha show double visceral organs, double gills, and normally a double-chambered heart.

Neritimorpha
Neritimorpha is a taxonomic grouping, an unranked major clade of snails, gastropod mollusks. This grouping includes land snails, sea snails, slugs, some deepwater limpets, and also freshwater snails. Neritimorpha contains around 2,000 extant species. Some Neritimorphs are commonly kept as pets. This clade used to be known as the superorder Neritopsina. The clade Neritimorpha is, based on optimal phylogenetic analysis, deemed monophyletic. Etymology The clade’s name, Neritimorpha, is from the Ancient Greek νηρίτης (nērī́tēs 'Nerite') and μορφή (morphḗ 'form'). Geologic History and Evolution Neritimorpha has an extremely rich geologic history, going back to early Ordovician. This clade has been considered to be a leftover of early gastropod diversification. 1997 taxonomy According to the taxonomy of the Gastropoda (Ponder & Lindberg, 1997) Neritopsina is a gastropod superorder in the subclass Orthogastropoda.
