摘要：The first finding of a freshwater snail, Sibirenauta sibiricus (Westerlund, 1877), in one of the lakes on Wrangel Island (north-eastern Russia) is reported. No freshwater mollusc species have hitherto been known from this island. Specimens from the island are morphologically compared with the type series of the species. How aquatic molluscs may have migrated to the Arctic island is briefly discussed.Keywords: Arctic; freshwater snails; Physidae(Published: 19 August 2015)To access the supplementary material for this article, please see supplementary files in the column to the right (under Article Tools).Citation: Polar Research 2015, 34, 23889, http://dx.doi.org/10.3402/polar.v34.23889
