Abstract

Palearctic Radix auricularia (Linnaeus, 1758) inhabiting open littoral zone near the Zarechnoye settlement (6 km from the Severobaikalsk town) identified from anatomy show a high shell variability and can be subdivided into two morphs: with low and high spire. The empty shells of this species have been found over the past six years within green algae washed ashore of this area.
