Mysida

Mysida is an order of small, shrimp-like crustaceans in the malacostracan superorder Peracarida. Their common name opossum shrimps stems from the presence of a brood pouch or "marsupium" in females. The fact that the larvae are reared in this pouch and are not free-swimming characterises the order. The mysid's head bears a pair of stalked eyes and two pairs of antennae. The thorax consists of eight segments each bearing branching limbs, the whole concealed beneath a protective carapace and the abdomen has six segments and usually further small limbs.

Mysidae is the largest family of crustaceans in the order Mysida, with over 1000 species in around 170 genera.

Mysis is a genus of mysid crustaceans in the family Mysidae, distributed mainly in the coastal zone of the Arctic and high boreal seas. Several species also inhabit northern freshwater lakes and the brackish Caspian Sea. Fifteen species are recognized. Body lengths range from .

Petalophthalmidae is a family of marine crustaceans in the order Mysida, the opossum shrimps.

Heteromysis (from Greek heteros meaning ‘different’, and mysis, a genus name Mysis) is a genus of marine mysid crustaceans (opossum shrimps) from the family Mysidae, associated with various shallow-water invertebrates. The name describes differentiation of its pereiopods (thoracic appendages) as possible adaptation to commensal life-style. Heteromysis is one of the largest mysid genera, containing more than 100 species. The genus is distributed globally, but predominantly in tropical and subtropical waters.

Neomysis (from the Greek affix neo-, "new", and the genus name Mysis) is a genus of opossum shrimp (mysid crustacean) from the family Mysidae, distributed in the coastal zone of temperate seas of the Northern Hemisphere and South America. Several species, particularly from the West Pacific, are also found in fresh and brackish waters. The genus contains the following 18 species:

Paramysis (from the Greek affix '', "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).

Mysidopsis is a genus of mysid shrimps in the family Mysidae. The sensitivity of these shrimps to water quality makes them suitable for bioassays. Mysidopsis bahia and Mysidopsis almyra, which are used frequently to test for pesticides and other toxic substances, are now classified as Americamysis bahia and Americamysis almyra.

Siriella is a genus of mysid crustaceans form the family Mysidae, consisting of approximately 90 species. Found in all seas except cold Arctic and Antarctic waters, the genus is most diverse in tropics.

Praunus is a genus of mysid shrimp, comprising three species: Praunus flexuosus (Müller, 1776) Praunus inermis (Rathke, 1843) Praunus neglectus (G. O. Sars, 1869) When originally named in 1814 by William Elford Leach, the genus contained P. flexuosus (the type species), and a second species, "P. integer", which is now known as Neomysis integer.

Americamysis is a genus of mysid shrimps in the family Mysidae. The sensitivity of these shrimps to water quality makes them suitable for bioassays. Americamysis bahia and Americamysis almyra, which are used frequently to test for pesticides and other toxic substances, are often referred to as Mysidopsis bahia and Mysidopsis almyra in the literature.
