Cycloneritimorpha
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. Taxonomy The taxonomy of Cycloneritida is based on work by Kano et al. (2002) that recognizes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Neritopsoidea
Neritopsoidea is a taxonomic grouping, a superfamily of sea snails, marine gastropod mollusks in the clade Cycloneritimorpha, within the clade Neritimorpha, (according to Bouchet & Rocroi, 2005), or in the order Neritoina within superorder Cycloneritimorpha within the subclass Neritimorpha, (according to Bandel, 2007). Taxonomy 1997 taxonomy Neritopsoidea was placed in the order Neritoida, the superorder Neritopsina and the subclass Orthogastropoda according to the taxonomy of the Gastropoda by Ponder & Lindberg, 1997. 2005 taxonomy This family consists of the following six families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * family Neritopsidae * † family Cortinellidae * † family Delphinulopsidae * † family Plagiothyridae * † family Pseudorthonychiidae * family Titiscaniidae 2007 taxonomy Bandel (2007)Bandel K.

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. The superfamily Palaeotrochoidea is con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nerita Plicata
''Nerita plicata'' is a species of tropical sea snail, a marine gastropod mollusk in the family Neritidae, the nerites. This species is found throughout the Indo-West Pacific. Characteristics The ''Nerita plicata'' is characterized by its 30 mm shell height with its width being about the same. Their exterior is generally dull white or pink with ribs sometimes being black. Habitat This species lives high up in the intertidal zone The intertidal zone, also known as the foreshore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range). This area can include several types of habitats with various species o ..., on rocks. ''N. plicata'' has ridges on its shell that helps it stay cool when exposed at low tide by radiating heat away. Reproduction The ''Nerita plicata'' reproduces through copulation between male and female. After mating, females will deposit egg capsules which will eventually hatch into ...

Hydrocenoidea
Hydrocenidae is a taxonomic family of minute land snails or cave snails with an operculum, terrestrial gastropod mollusks or micromollusks in the clade Cycloneritimorpha. Hydrocenidae are widespread across the Palearctis and Africa, but reach their highest diversity in the Oriental, Australian, and Oceanian regions. The family is poorly known and has not been revised in the past 140 years and as a consequence, the status of the various genus names (including '' Georissa'') is uncertain. Hydrocenidae is the only family in the superfamily Hydrocenoidea. This family has no subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Description The animal have no gill, but a pulmonary cavity. Tentacles are short and large. The eyes are prominent, situated at the upper or outer base of the tentacles. The foot is short, oval and obtuse. The denticle (tiny teeth) of radula have the formula ∞ 1, (1 + 1 + 1), 1 ∞. The central denticles are small and ...
