Nystia
''Nystia'' is an extinct genus of fossil freshwater snails, aquatic gastropod molluscs in the family Truncatellidae.Kadolsky D. (1988). "Mollusken aus dem Oligozän von Sieblos a.d. Wasserkuppe/Rhön". ''Beitrage zur Naturkunde in Osthessen'', Fulda, 24: 99-129. pages 103-105. The genus ''Nystia'' was previously classified within the Stenothyridae or the Micromelaniidae. It is currently classified within the Truncatellidae according to Kadolsky (1988). Distribution The distribution of the genus ''Nystia'' includes France and the Czech Republic. Species Species in the genus ''Nystia'' include: * ''Nystia duchasteli'' (Nyst, 1836) - synonym: ''Paludina duchasteli'' Nyst, 1836, type species, from Eocene of France * ''Nystia lenoiri'' * ''Nystia rubeschi'' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truncatellidae
Truncatellidae, common name the "looping snails", is a Family (biology), family of small amphibious snails, with gills and an operculum (gastropod), operculum, semi-marine gastropod mollusks or micromollusks. Shell description This family of snails have small gastropod shell, shells which lose their apical whorl (mollusc), whorls as they continue to grow, giving the shells a truncated and cylindrical appearance. Subfamilies The family Truncatellidae consists of two subfamilies (according to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * subfamily Truncatellinae Gray, 1840 * subfamily Geomelaniinae Kobelt & Möllendorff, 1897Kobelt & Möllendorff (1897). ''Nachrichtsblatt der Deutschen Malakozoologischen Gesellschaft'' 29(5-6): 74. Genera Genera within the family Truncatellidae include: Truncatellinae * ''Truncatella (gastropod), Truncatella'' Antoine Risso, Risso, 1826 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Freshwater Snail
Freshwater snails are gastropod mollusks that 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 gastropod shell, shell, with very few exceptions. Some groups of snails that live in freshwater Respiratory system, respire using gills, whereas Pulmonata, 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 feeding, filter feeders. Freshwater snails are indirectly among the deadliest animals to humans, as they carry parasitic worms that cause schistosomiasis, a disease estimated to kill between 10,000 and 200,000 people annually. There are thousands of known species, and at least 33–38 independent Lineage (evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
Gastropods (), commonly known as slugs and snails, belong to a large Taxonomy (biology), taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and sea slug, slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca. It 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 Furongian, Late Cambrian. , 721 family (taxonomy), families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently neontology, extant living fossil, with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusc
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
