of the Ponto-Caspian Basin; some of them naturally spread more than up large rivers, including the Volga, Don, Dnieper and Danube. A number of Ponto-Caspian species have been introduced outside the native range. Marine species from the Atlantic Ocean and Mediterranean Sea have probably descended from ancient Ponto-Caspian populations.

Diversity

There are 24 species classified into 7 subgenera. Body length ranges from . The largest species, like ''P. eurylepis'', ''P. inflata'', are found only in the Caspian Sea. Generic characters: subrostral plate; large eyes on short stalk;
