Fig. 1 in Taxonomic, ecological and morphological diversity of Ponto-Caspian gammaroidean amphipods: a review
Fig. 1 Overview map of the Ponto-Caspian region, which includes the Black, Azov, Caspian and Aral seas as well as the adjacent lagoons and lower river stretches. Red numerals indicate the number of valid endemic Ponto-Caspian species (including non-Gammaroidea) in various regions (Azov and Black seas shown together). Note that the Azov/Black Sea region shares 43 species with the Caspian Sea. The area delimited with transparent white indicates the maximum extent of the Paratethys Sea during the Late Miocene (ca. 11 Ma) (Palcu et al., 2021). All of the contemporary seas are remnants of the Paratethys
