The age-related changes in hemolymph cellular composition of snail Lymnaea stagnalis (Gastropoda, Pulmonata) obtained from individuals of a natural population (the river Pripayt, Gomel region, Belarus) as well as in the spectrum of cytomorphological traits of hemocyte genetic damages have been studied. The percentage of the distinguished hemolymph cell types during the chosen age period was not revealed to change. The percentage of cells with different morphological attributes of cell death varied during ageing. The tendency to increase in the total level of dying cells was observed.

Key words: hemocytes, micronuclei, cell death, hemolymph, cellular composition, ageing, snail Lymnaea stagnalis.
