The analysis of a number of morphometric data has led to the conclusion that external distinctions observed are a consequence of morphological plasticity reflecting the peculiarities of habitats. Hence, populations existing in the Black- Azov Seas basin should not be classified as several subspecies. %8 2000-02-01
