In this study, a total of 115 Rana ridibunda specimens (64 males ; 51 females) from the Black Sea region (10 localities) have been investigated. Morphometric measurements of the samples and some of their ratios derived from them comprise the morphological investigation together with pattern and coloration analyses. It was found that the populations examined belong to the nominal subspecies of R. r. ridibunda.
