Аннотация

The taxonomy of family Naticidae gastropods inhabiting the Eurasian Arctic and adjacent regions is mainly based on shell features while anatomical data is used rarely. The aim of this study is to describe interand intraspecific variability of some radular characters and to estimate their suitability for species-level taxonomy. In total eighteen radulae of four naticid species (Amauropsis islandicus, Cryptonatica affinis, Euspira pallida, Euspira tenuistriata) were studied using a scanning electron microscopy. Statistical analysis of six morphometric characters describing shape of radular teeth did not reveal any significant differences between species. Three specimens of Cryptonatica affinis were separated on scatterplot from the other snails. Previous suggestions on the change in the number of denticles in the central and marginal teeth during the snails’ growth were not confirmed.
