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.

Distribution[edit]

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

Habitat[edit]

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

Radix peregra

Taxonomy[edit]

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]
