Radix peregra, previously known as Lymnaea peregra or Lymnaea pereger, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod in the family Lymnaeidae, the pond snails.

There is more than one named variety or form of this snail.


This small pond snail is found in Europe, Newfoundland and north Asia, in countries and islands including:


This species is common in slow-moving or still water.[4]

Radix peregra


The taxonomic status of certain species in the genus Radix has been disputed. Remigio (2002) reported sequence divergence within the 16S mitochondrial gene of Radix peregra and Radix ovata.[5] Furthermore, the shell morphology and alloenzyme data indicated that Radix peregra and Radix ovata are distinct.[6][7]

In contrast, Bargues et al. (2001) considered on the basis of ITS-2 sequence analysis, that R. peregra, R. ovata, and R. balthica are in fact a conspecific species.[8]
