Journal: Folia Malacologica
Year: 2020

The first record of Donacilla cornea (Poli) from Ukrainian beaches since 1960 is presented. The populations from the northern Black Sea were studied for their size and colour polymorphism. The maximum shell length was 26.05 mm, thus exceeding the previously reported values. The shell size differences between the populations and the similarity of shell shape indices were confirmed by one-way ANOVA. The negative allometry of height and width to length was confirmed by the t-test of linear regressi
