Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a class in superclass Multicrustacea. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.
The Cyclopoida are an order of small crustaceans from the subclass Copepoda. Like many other copepods, members of Cyclopoida are small, planktonic animals living both in the sea and in freshwater habitats. They are capable of rapid movement. Their larval development is metamorphic, and the embryos are carried in paired or single sacs attached to first abdominal somite.
Arctodiaptomus kamtschaticus is a species of crustacean in the family Diaptomidae. It is endemic to lakes in Kamchatka, eastern Russia, and is listed as a vulnerable species on the IUCN Red List.
Dussartius baeticus is a species of crustacean in the family Diaptomidae. It is endemic to the Iberian Peninsula, having been found in south-eastern Spain, and in the waters of the Tagus estuary, the Caniçada reservoir, and four reservoirs in the Mondego system in Portugal.
Hesperodiaptomus is a genus of copepods in the family Diaptomidae, containing 18 species. Two species – Hesperodiaptomus augustaensis and Hesperodiaptomus californiensis – are endemic to the United States and listed as vulnerable species on the IUCN Red List.
Neutrodiaptomus is a genus of copepods in the family Diaptomidae. The Japanese endemic species N. formosus is listed as Data Deficient on the IUCN Red List. The genus Neutrodiaptomus contains the following species:
Diaptomidae is a family of freshwater pelagic copepods. It includes around 50 genera:
Canthocamptidae is a family of copepods. Most of the 700 species are confined to fresh water, although there are also marine species. It contains the following genera:
Ectinosomatidae is a family of the Harpacticoida, a huge group of crustaceans belonging to the subclass Copepoda. Like most of their relatives, they are usually benthic inhabitants of marine environments. Ectinosomatidae commonly inhabit sediment and fragments of dead corals or glass sponges, and occasionally algae and bryozoans, in the deep oceans. In the epifaunal species, the first leg pair is often modified to allow the animals a better grip on the substrate.
Paradiaptomus africanus is a species of copepod in the family Diaptomidae. As an example occurrence, Lovenula africana is found within the Makgadikgadi Pans, a seasonal hypersaline wetland in Botswana.
The Chitonophilidae are a family of parasitic copepods, with these genera:
Paracalanidae is a family of Calanoid copepods, consisting of the following genera:
Acartia teclae is a species of copepod belonging to the family Acartiidae. This species was discovered when specimens previously identified as Acartia clausi were examined and found to belong to a separate species. This species appears to have a similar range to, and occupies similar brackish estuarine habitats as, Acartia lefevreae but differs in the absence of spines on the dorsal part of the posterior body segment (metasome).
Cyclops bicuspidatus is a planktonic species of copepod found throughout the world, except Australia, and characteristic of the Great Lakes of North America. It is a deep water species found throughout the year with peak abundance occurring in May or June. Males grow up to 0.8–1.0 millimetre (0.031–0.039 in) long, while females are larger at 0.9–1.6 mm (0.035–0.063 in).
Centropagidae is a family of copepods in the order Calanoida. Its members are particularly known as plankton in coastal waters and in fresh water in Australia and southern South America. They are also found on subantarctic islands and in lakes in Antarctica.
Phaennidae is a family of planktonic copepods, found in pelagic or benthopelagic waters. It contains the following genera:
Sinodiaptomus is a genus of freshwater copepods in the family Diaptomidae, found in Asia and Palaearctic regions. The Japanese Sinodiaptomus valkanovi has established non-indigenous populations in California, Bulgaria and New Zealand, although only the New Zealand population persists due to destruction of the habitat in California and Bulgaria. The genus was originally described as a subgenus of Diaptomus, containing only Sinodiaptomus chaffanjoni, but now contains five species:
Boeckella palustris is a species of copepod found in South America. It inhabits shallow pools, including the highest body of water ever to have yielded a crustacean, at an altitude of 5,930 m (19,460 ft) in the Andes. It was described independently by two scientists in 1955, using material brought back by different European expeditions to the same region.
Temoridae is a family of copepods, containing the following genera:
Metridinidae is a family of copepods, comprising three genera – Gaussia, Metridia and Pleuromamma. It has also been referred to as "Metridiidae", but following a petition to the International Commission on Zoological Nomenclature, that name has been restricted to the family Metridiidae Carlgren, 1893, based on the anthozoan genus Metridium. All species in the family can produce blue-green bioluminescence; the light is produced in glands, whose position varies between genera.
