Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic, some are benthic, several species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, puddles, damp moss, or water-filled recesses of plants (phytotelmata) such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators.
Oncaea is a genus of copepods. The genus contains bioluminescent species. Unlike other bioluminescent copepods, Oncaea have an internal (non-secreted) bioluminescence. Oncaea contains the following species:
Paracalanidae is a family of Calanoid copepods, consisting of the following genera:
Acartia is a genus of marine calanoid copepods. They are epipelagic, estuarine, zooplanktonic found throughout the oceans of the world, primarily in temperate regions.
Temoridae is a family of copepods, containing the following genera:
Euaugaptilus is a genus of copepods. The genus contains bioluminescent species.
Augaptilidae is a family of copepods.
Mormonillidae is a family of planktonic marine copepods, the only member of the order Mormonilloida. There are five known species in two genera:
Centropages is a genus of copepods in the family Centropagidae with 34 known marine species.
Artotrogidae is a family of copepods in the order Siphonostomatoida.
Neocalanus is a genus of marine copepods. They are a dominant component of the open water ecosystems of the northern Pacific Ocean. Neocalanus are large copepods, reaching body lengths of more than 8 mm (0.31 in) in Neocalanus plumchrus.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described non-hexapod 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.
Temora is a genus of copepods in the family Temoridae. The World Register of Marine Species lists the following species:
Temora longicornis is a species of copepod in the family Temoridae. It is found in marine environments on both sides of the Atlantic Ocean.
Temora stylifera is a copepod primarily found in the Atlantic and surrounding waters.
Oithona is a planktonic crustacean genus found in marine, brackish, fresh water environments. Oithona has been described as the most ubiquitous and abundant copepod in the world's oceans. It was first described by Baird in 1843 using the species Oithona plumifera as taxon type.
Temora turbinata is a copepod in the Temoridae family. It is an epipelagic species, having been recorded in coastal waters around the world. It was first described in 1849 by American scientist James Dwight Dana.
Temora kerguelensis is a marine copepod in the Temoridae family. It was first described in 1911 by English oceanographer Richard Norris Wolfenden. The adult specimen measures around 2 mm. It has been recorded in sub-Antarctic waters of the southern Indian Ocean near Kerguelen Islands.
Eurytemora is a genus of copepods in the family Temoridae.
Candacia is a genus of copepods in the order Calanoida. It is the only genus in the monotypic family Candaciidae.
