Paramysis (from the Greek affix para-, "near", "beside", and the genus name Mysis) is a genus of mysid crustaceans (Mysidacea) in family Mysidae, distributed in coastal zone of low boreal East Atlantic Ocean, Mediterranean Sea and the basins of Black Sea, Sea of Azov and Caspian Sea (Ponto-Caspian Basin).
The majority of Paramysis species are brackish- or freshwater endemics of the Ponto-Caspian Basin; some of them naturally spread more than 500 kilometres (310 mi) 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.[1]
