Viviparus, commonly known as the river snails, is a genus of large, freshwater snails with an operculum, aquatic gastropod mollusks. [2]
They are primitive members of the clade Caenogastropoda. The old name of the genus was Paludina.
This genus is palaearctic in distribution, [3] and is known from the Jurassic to the Recent. [4]
Viviparus belongs to the subfamily Viviparinae. Its taxonomy is currently under development and many of its species are often included in other related genera. It includes the following species: [5]
