WAnomopoda is a suborder of the order Cladocera. These crustaceans, a type of water flea, are members of the Class Branchiopoda. The Anomopoda typically have five pairs of thoracic limbs, but sometimes have six pairs. The head of the Anomopoda lacks a clear separation from the trunk and the posterior, while the abdomen area gradually merges with the anterior of the trunk.
WArchaebranchinecta barstowensis is a species of fairy shrimp (Anostraca) that inhabited California during the Middle Miocene. Its fecal material is abundant in the concretions from the Barstow Formation. A limited number of whole specimens have been found, and they represent the "best-preserved fossil anostracan known to date". The closest relative of A. barstowensis appears to be Archaebranchinecta pollicifera from the surroundings of Lake Titicaca, and the two have been separated from the genus Branchinecta as the new genus Archaebranchinecta.
WArtemia monica, the Mono Lake brine shrimp, is a species of brine shrimp, endemic to Mono Lake in California, United States.
WBosmina is a genus in the order Cladocera, the water fleas. Its members can be distinguished from those of Bosminopsis by the separation of the antennae; in Bosminopsis, the antennae are fused at their bases.
WBosminidae is a family of anomopods in the order Diplostraca. There are at least 3 genera and 40 described species in Bosminidae.
WBranchinecta is a genus of crustacean in family Branchinectidae. It includes around 50 species, found on all continents except Africa and Australia. Branchinecta gigas, the giant fairy shrimp, is the largest species in the order, with a length of up to 10 centimetres (4 in), and Branchinecta brushi lives at the highest altitude of any crustacean, at 5,930 metres (19,460 ft), a record it shares with the copepod Boeckella palustris. A new genus, Archaebranchinecta was established in 2011 for two species previously placed in Branchinecta.Branchinecta achalensis Cesar, 1985 Branchinecta belki Maeda-Martínez, Obregón-Barboza & Dumont, 1992 Branchinecta brushi Hegna & Lazo-Wasem, 2010 Branchinecta campestris Lynch, 1960 – pocket-pouch fairy shrimp Branchinecta coloradensis Packard, 1874 – Colorado fairy shrimp Branchinecta constricta Rogers, 2006 Branchinecta conservatio Eng, Belk & Eriksen, 1990 – conservancy fairy shrimp Branchinecta cornigera Lynch, 1958 – horned fairy shrimp Branchinecta dissimilis Lynch, 1972 – Great Basin fairy shrimp Branchinecta ferox (M.

A second species, originally described as "Prolepidurus oblongus", from the Jehol fauna, was redescribed as C. oblongus.

WCyzicidae is a family of crustaceans in the order Spinicaudata. They are distinguished from the family Leptestheriidae by the absence of a rostral spine. Some members of Cyzicidae are known to burrow through mud, leading to speculation that they may be filter feeders, but Martin reports that their mouthparts are indistinguishable from Leptestheriidae, which are believed to be grazers.
WCyzicus is a genus of clam shrimps in the family Cyzicidae. Identified by Jean Victoire Audouin in 1837, the genus was reidentified as Caenestheriella by Eugen von Daday in 1910.

WDexteria floridana is an extinct species of fairy shrimp in the family Chirocephalidae, the only species in the genus Dexteria. It was endemic to Florida, where it was known from a single pool, south of Gainesville. It was originally described by Ralph W. Dexter in 1953 as a species of Eubranchipus. The species was declared extinct on October 5, 2011 because it was found that the only known pool of water that contained the known population was filled in for development, thereby killing the shrimps.
WEubranchipus is a genus of brine shrimp and fairy shrimp in the family Chirocephalidae. There are about 16 described species in Eubranchipus.
WEvadne is a genus of onychopods in the family Podonidae. There are at least four described species in Evadne.

WJeholops is an extinct genus of notostracan which existed in the Yixian Formation, inner Mongolia, China during the early Cretaceous period. It was described by Thomas A. Hegna and Ren Dong in 2010, and the only species is Jeholops hongi.
WLepidurus is a genus of small crustaceans in the order Notostraca. It is the larger of the two extant genera of the tadpole shrimps, the other being Triops. They are commonly found in vernal pools and survive dry periods with the help of long lasting resting eggs.
WLepidurus arcticus is a species of tadpole shrimp which inhabits both ephemeral pools and permanent freshwater lakes of Norway, Greenland, Finland, Sweden, Svalbard, Iceland, Russia and the Kuril Islands.
WLimnadiidae is a family of crustaceans in the order Spinicaudata that live in seasonal wetlands, inland saline pools and lakes. They are found on all the world's continents except Antarctica, and are distinguished from other families in the same order by the fact that the cephalic fornicies do not extend forwards. The family contains eight extant genera:Afrolimnadia Rogers et al., 2012 Calalimnadia Rabet & Rogers, 2012 Eulimnadia Packard, 1874 Imnadia Hertzog, 1935 Limnadia Brongniart, 1820 Limnadopsis Spencer & Hall, 1896 Metalimnadia Mattox, 1952 Paralimnadia Sars, 1896
WLioestheria are an extinct genus of crustaceans that thrived from the Carboniferous to the Cretaceous. They fed on detritus, being very small slow moving, nektonic organisms that filter fed as they floated. They have been found in both marine and freshwater environments.
WMoina is a genus of crustaceans within the family Moinidae. The genus was first described by W. Baird in 1850. They are referred to as water fleas but are smaller than their more well-known cousins: the larger Daphnia magna and the medium-sized Daphnia pulex. This genus demonstrates the ability to survive in waters containing low oxygen levels as well as high salinity and other impurities, including salt pans, and commonly eutrophication. An example of such an extreme habitat is the highly saline Makgadikgadi Pans of Botswana, which supports the species Moina belli prolifically.

WTriops granarius is a species of tadpole shrimp with a broad distribution from Africa and the Middle East to China and Japan, although there are indications that it, as presently defined, is a species complex. They have elongated bodies and large flaps. Triops granarius can be kept as pets in home aquaria. Their life expectancy is up to 90 days, and in that time they can grow more than 6 cm in length.
WTriops newberryi is a species of Triops found on the western coast of North America, commonly in valleys throughout the states of Washington, Oregon, California, and small areas of Nevada, Utah, New Mexico, and Mexico, with at least one disjunct population in Kansas. They are found in vast numbers though in the Coachella Valley in California. T. newberryi has been reported to have potential as a biocontrol agent for larval mosquitoes breeding in seasonally-flooded habitats. T. newberryi is genetically distinct from T. longicaudatus, the dominant species in the Central United States.
