Amnicolidae
Amnicolidae is a family of small freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the superfamily Rissooidea. This family is in the clade Littorinimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family was previously considered to be a subfamily of Hydrobiidae. Subfamilies The family Amnicolidae consists of 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): *Subfamily Amnicolinae Tryon, 1863, synonymised with: **Tribe Erhaiini Davis & Kuo, 1985 **Subfamily Lyogyrinae Pilsbry, 1916 **Subfamily Parabythinellinae Radoman, 1976 **Tribe Pseudobythinellini Davis & Chen, 1992 *Subfamily Baicaliinae P.

Stefan Clessin
Stefan Clessin (13 November 1833, in Würzburg – 21 December 1911, in Regensburg) was a German malacologist. He served as a military officer, and from 1862 worked for the Bavarian railways. He was an editor of the '' Malakozoologische Blätter'' and made major contributions to Martini and Chemitz' ''Systematisches Conchylien-Cabinet''. He conducted research of fossil mollusks as well as living species. Bibliography * ''Die mollusken-fauna der umgegend von Augsburg'' (1871); Bericht des Naturhistorischen vereins in Augsburg, bd.

Mollusk
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 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 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 and even terrestrial species. 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 extant i ...

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] |
