World list of lophogastrida, stygiomysida and mysida

This World List of all species of Lophogastrida, Stygiomysida and Mysida ever described, is part of the World Register of Marine Species (WoRMS), a global initiative to provide a register of all marine organism names.

The peracarid crustacean orders Mysida, Lophogastrida and Stygiomysida were formerly grouped under the name “Mysidacea”. Database concepts 6th edition pdf Although the treatment in three separate orders is now accepted, we have chosen to present mysids, lophogastrids and stygiomysids in the same web interface. Data recovery utility The higher classification (orders, families, subfamilies) follows Meland & Willassen (2007), and the fossil order of Pygocephalomorpha is also included in the database.


Mysids, lophogastrids and stygiomysids are shrimplike in appearance, the majority of species being between 5 mm and 25 mm in length. Data recovery from hard drive Due to the presence of oostegites forming a ventral female marsupium, mysids are often referred to as opossum shrimp. Database objects The “Mysidacea” have earlier been allied with decapods, euphasiids, stomatopods, and even nebaliaceans (see Tattersall & Tattersall, 1951, for taxonomic history), but are readily distinguished from other shrimplike crustaceans, and also the remaining Peracarida, by the presence of a statocyst in the proximal part of the endopods of the uropods. Data recovery raid 5 Since this balance organ is missing in the more “primitive” mysid families (Lophogastridae, Gnathophausiidae, Eucopiidae and Petalophthalmidae) some confusion can arise, but they are still easily distinguished from euphasiids and carideans by the presence of a well developed brood pouch in mature females.

Mysids have a worldwide distribution. Database architect Most species are free living and marine, the majority of species inhabiting coastal and open sea waters. Data recovery options A few species are adapted to continental fresh water, and these are also included in the database. Database jobs Some species, as seen in the tribe Heteromysini, have also taken on a commensal habit, often described in association with sponges, sea anemones, corals, and hermit crabs. H2 database file Several taxa have also been described from different groundwater habitats, marine and anchialine caves. R studio data recovery serial key In addition to having pelagic forms, mysid species are often found associated with the benthic boundary layer (the hyperbenthos, sensu Mees & Jones, 1997), burrowing, or hovering immediately above or resting on the sediment surface. Database query languages The majority of Mysidacea are filter feeders and generally regarded as omnivores, feeding on algae, detritus, and zooplankton (Mauchline, 1980). P d database Pelagic forms filter particles during swimming while benthic species, common for the tribe Erythropini, are often seen feeding on small particles which they collect by grooming their carapace and legs (Fosså, 1986). Database 101 In other species tendencies towards a strict carnivorous habit are observed, and then often seen as scavengers, feeding on carcasses of polychaetes, copepods, amphipods and even other mysids, but true predators on zooplankton are also described (Tattersall & Tattersall, 1951).

The order Mysida (2 families, 175 genera, 1144 species) contains the largest number of species across the most diversity of habitats, with species found in subterranean, fresh, brackish, coastal, and surface to deep-sea habitats.

Database administrator jobs In comparison, the Lophogastrida (3 families, 9 genera, 53 species) are mainly meso- to bathypelagic while the Stygiomysida (2 families, 2 genera, 16 species) are found primarily in subterranean waters.

The taxonomy in the database is edited and updated by volunteer experts, assisted by the database management team. Data recovery joondalup Currently there are 2,001 name records, of which 1,262 are valid names, the rest invalid synonyms, nomina dubia, etc. Database of genomic variants The editors aim to resolve all conflicting or out of date records promptly when noticed, and we hope you will tell us about any duplications or other confusions you find. Database viewer Taxonomists are encouraged to send us a copy of new publications so that we can see the details of new and changed nomenclature.
