Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them.
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:
Acartiidae is a family of calanoid copepods distinguishable by the rostral margin not being extended. They are epipelagic, planktonic animals, not being found below a depth of 500 metres (1,600 ft). There are over 100 described species distributed throughout the world's oceans, mainly in temperate areas.
Shiinoidae is a family of parasitic copepods.
Acartia is a genus of marine calanoid copepods. They are epipelagic, estuarine, zooplanktonic found throughout the oceans of the world, primarily in temperate regions.
Acartia clausi is a species of marine copepod belonging to the family Acartiidae. This species was previously thought to have a worldwide distribution but recent research has restricted its range to coastal regions of the north-eastern Atlantic Ocean as far north as Iceland, the Mediterranean Sea and the Black Sea, with specimens from other regions assigned to different species.
Acartia lefevreae 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. Its range overlaps with that of A. clausi, being found in the western Mediterranean and the north east Atlantic as far north as the English Channel, but it tends to be found in more brackish habitats such as estuaries.
Acartia omorii is a species of marine 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 is found around the coast of Japan. It is similar to A. clausi but lacks the prominent spines on the dorsal part of the posterior body segment (metasome).
Acartia hudsonica is a species of marine copepod belonging to the family Acartiidae. Acartia hudsonica is a coastal, cold water species that can be found along the northwest Atlantic coast.
Acartia ensifera is a species of marine copepod belonging to the family Acartiidae. This is a slender copepod, around 0.8–0.9 mm (0.031–0.035 in) in length, with distinctively long caudal rami. It is found around the coasts of New Zealand.
Acartia jilletti is a species of marine copepod belonging to the family Acartiidae. This species has a total length of up to 1 mm. It is very similar to Acartia ensifera but the female can be distinguished by the shorter caudal rami and the male by the relative length of spines on the fifth pair of legs. This species has been recorded from scattered locations around the coast of New Zealand.
Acartia tranteri is a species of marine copepod belonging to the family Acartiidae. This Australian species is related to the New Zealand species A. ensifera, A. jilletti and A. simplex but can be distinguished by the lack of any ventral prominence posterior to the genital opening in the female and the presence of posterior spines on the metasome of the male. It is found off the southern coast of Australia.
Phaennidae is a family of planktonic copepods, found in pelagic or benthopelagic waters. It contains the following genera:
Augaptilidae is a family of copepods.
Acartia tonsa is a species of marine copepod in the family Acartiidae.
Tortanidae is a family of copepods within the order Calanoida. The tropicus group of this species can be found in the tropical and subtropical waters of Southeast Asia. The groups are distinguishable by their genitals and their tails.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
Janet Mary Grieve, also known as Janet Bradford-Grieve and Janet Bradford, is a New Zealand biological oceanographer, born in 1940. She is researcher emerita at the National Institute of Water and Atmospheric Research in Wellington. She has researched extensively on marine taxonomy and biological productivity. She was president of both the New Zealand Association of Scientists (1998–2000) and the World Association of Copepodologists (2008–11).
Aetideidae is a family of copepods belonging to the order Calanoida.
