Морфологические и оптические свойства и эволюционные изменения щупальцевого эпидермиса и роговицы глаз наземных брюхоногих моллюсков (Pulmonata, Stylommatophora)

Morphological and optical properties of tentacular epidermis and cornea of the eyes of some species of terrestrial gastropod pulmonate molluscs were studied and their evolutionary transformations were estimated. It was demonstrated that all examined properties of tentacular epidermis and cornea of these species are typical for terrestrial pulmonates. In the course of evolution tentacular epidermis of terrestrial pulmonate molluscs was modified to less extent than cornea, and both these structures underwent minor changes in comparison with analogous structures of the eyes of marine prosobranch molluscs.
