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).

Biogeography

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]

Diversity

There are 23 species[2][3][4] classified into 8 subgenera.[3][5][6] Body length ranges from 1 to 4 centimetres (0.4 to 1.6 in). The largest species, like P. eurylepis, P. inflata, are found only in the Caspian Sea. Generic characters: subrostral plate; large eyes on short stalk; antennal scale with smooth outer margin, ended by strong spine, and distal segment rudimentary with five setae; four segments of pereiopod 1–4 carpopropodus; five segments in pleopod 4 of male.[3] Consumed by fishes; particularly important for juvenile sturgeons and zander.[5]

Two extinct species, previously included into this genus,[7][8] have been recently moved into extinct genus Sarmysis.[9]
