Chydoridae is a family of water fleas in the order Anomopoda. There are more than 50 genera and 520 described species in Chydoridae. [1] [2] [3] A lot of Chydoridae species are non-native species, many of which pose a great threat to aquatic ecosystems. [4]

<span class="mw-page-title-main">Branchiopoda</span> Class of crustaceans

Branchiopoda is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca, Notostraca and the Devonian Lepidocaris. They are mostly small, freshwater animals that feed on plankton and detritus.

<i>Daphnia</i> Genus of crustaceans

Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas. Daphnia spp. live in various aquatic environments ranging from acidic swamps to freshwater lakes and ponds.

<span class="mw-page-title-main">Anostraca</span> Order of crustaceans

Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are referred to as fairy shrimp. They live in vernal pools and hypersaline lakes across the world, and they have even been found in deserts, ice-covered mountain lakes, and Antarctic ice. They are usually 6–25 mm (0.24–0.98 in) long. Most species have 20 body segments, bearing 11 pairs of leaf-like phyllopodia, and the body lacks a carapace. They swim "upside-down" and feed by filtering organic particles from the water or by scraping algae from surfaces, with the exception of Branchinecta gigas, or "giant fairy shrimp", which is itself a predator of other species of anostracans. They are an important food for many birds and fish, and some are cultured and harvested for use as fish food. There are 300 species spread across 8 families.

<i>Cyclops</i> (copepod) Genus of crustaceans

Cyclops is one of the most common genera of freshwater copepods, comprising over 400 species. Together with other similar-sized non-copepod fresh-water crustaceans, especially cladocera, they are commonly called water fleas. The name Cyclops comes from the Cyclops of Greek mythology, as they have a single large eye; in Cyclops, the eye may be either red or black.

Alona is a genus of cladocerans in the family Chydoridae. It is one of the largest genera of Cladocera, and is widely believed to be an artificial group which is in need of systematic revision; the type species is Alona quadrangularis. Around 240 names at the species level have been described in Alona; it is unclear how many of these are valid, or how they are related.

<i>Branchinecta</i> Genus of small freshwater animals

Branchinecta is a genus of crustacean in family Branchinectidae. It includes around 50 species, found on all continents except 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.

<i>Mesocyclops</i> Genus of crustaceans

Mesocyclops is a genus of copepod crustaceans in the family Cyclopidae. Because the various species of Mesocyclops are known to prey on mosquito larvae, it is used as a nontoxic and inexpensive form of biological mosquito control.

<i>Streptocephalus</i> Genus of small freshwater animals

Streptocephalus is a genus of fairy shrimp found in temporary waters in Africa, Australia, Eurasia, and Central and North America, following its ancient origin in Gondwana. It contains the following species:

<i>Bosmina</i> Genus of small freshwater animals

Bosmina 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.

<span class="mw-page-title-main">Diplostraca</span> Order of small freshwater animals

The Diplostraca or Cladocera, commonly known as water fleas, is a superorder of small, mostly freshwater crustaceans, most of which feed on microscopic chunks of organic matter, though some forms are predatory.

<i>Moina</i> Genus of small freshwater animals

Moina 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 related to the much larger Daphnia magna and the larger Daphnia pulex. This genus demonstrates the ability to survive in waters containing low oxygen levels, 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 prolific numbers of Moina belli.

<span class="mw-page-title-main">Daphniidae</span> Family of small freshwater animals

Daphniidae is a family of water fleas in the order Anomopoda.

<i>Leptodora</i> Genus of small freshwater animals

Leptodora is a genus containing two species of large, nearly transparent predatory water fleas. They grow up to 21 mm (0.83 in) long, with two large antennae used for swimming and a single compound eye. The legs are used to catch copepods that it comes into contact with by chance. Leptodora kindtii is found in temperate lakes across the Northern Hemisphere and is probably the only water flea species ever described in a newspaper; L. richardi is only known from eastern Russia. For most of the year, Leptodora reproduces parthenogenetically, with males only appearing late in the season, to produce winter eggs which hatch the following spring. Leptodora is the only genus in its family, the Leptodoridae, and suborder, Haplopoda.

<i>Daphnia <span style="font-style:normal;">(</span>Daphnia<span style="font-style:normal;">)</span></i> Subgenus of small freshwater animals

Daphnia is one of the three subgenera of the genus Daphnia, the others being Australodaphnia and Ctenodaphnia.

<i>Sida</i> (crustacean) Genus of small freshwater animals

Sida is a genus of ctenopods in the family Sididae. There are about five described species in Sida.

<span class="mw-page-title-main">Sididae</span> Family of small freshwater animals

Sididae is a family of ctenopods in the order Diplostraca. There are about 6 genera and at least 20 described species in Sididae. Some Sididae are non-native species.

<span class="mw-page-title-main">Macrothricidae</span> Family of arthropods

Macrothricidae is a family of anomopods in the order Diplostraca. There are about 17 genera and at least 80 described species in Macrothricidae.

<span class="mw-page-title-main">Podonidae</span> Family of small freshwater animals

Podonidae is a family of onychopods in the order Diplostraca. There are about 8 genera and at least 20 described species in Podonidae. A lot of them are non-native species, many of which pose a great threat to aquatic ecosystems.

Cercopagididae is a family of crustaceans belonging to the order Diplostraca. A lot of Cercopagididae species are non-native species, many of which pose a great threat to aquatic ecosystems.
