Bythinella Elenae
''Bythinella'' is a genus of very small freshwater snails, an Aquatic animal, aquatic gastropod mollusk in the family (biology), family Bythinellidae (according to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). These gonochoristic snails are small animals, with a shell length of about 2–4 mm.Bichain ''et al.'' (2007) ''Amnicola'' is a close relative, containing North American snails with essentially similar appearance and ecology. The scientific name means "small ''Bithynia (genus), Bithynia''"; the latter snail genus is somewhat similar at a casual glance (though much larger) but not at all closely related among the Rissooidea. Distribution The present genus occurs in Spring (hydrosphere), springs, and sometimes caves or groundwater, from Catalonia across central Europe to the Aegean Region of Turkey. In and around France a particularly high diversity of these snails is found. Due to the limited range and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bythinella Reyniesii
''Bythinella reyniesii'' is a species of very small freshwater snail, an Aquatic animal, aquatic gastropod mollusk in the family Amnicolidae. Distribution These snails live in spring (hydrosphere), springs. They were long believed to occur only in Andorra, List of non-marine molluscs of Austria, Austria, and parts of List of non-marine molluscs of France, France. This disjunct distribution was puzzling, until it was realized that the populations assigned to several other supposedly distinct species actually seem to all belong to one species. In fact, ''Bythinella reyniesii'' is probably widespread from western List of non-marine molluscs of Germany, Germany and nearby Belgium through central and eastern France to Andorra.Bichain J.-M..
