An interesting case of predominantly sinistral population of Lymnaea stagnalis (L.) (Gastropoda: Pulmonata: Lymnaeidae)

Maxim V. Vinarski

An interesting population of the common pond snail (L. stagnalis s.lat.) with a predominance of sinistral individuals is described. The discussion is based on a shell sample gathered by Russian malacologists Lindholm & Bäckmann in July 1917 in vicinity of Sankt-Petersburg (housed in the Zoological Institute of the Russian Academy of Science). Shell measurements, their ratios as well as possible explanations for the origin of this dimorphism are given.

Keywords: Lymnaea, sinistrality, shell coiling inversions, population genetics
