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]
There are 24 species [2] [3] [4] classified into 7 subgenera. [3] [5] [6] [7] 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, [8] [9] have been recently moved into extinct genus Sarmysis. [10]
