Calanoida
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. Description Calanoids can be distinguished from other planktonic copepods by having first antennae at least half the length of the body and biramous second antennae. However, their most distinctive anatomical trait is the presence of a joint between the fifth and sixth body segments. The largest specimens reach long, but most do not exceed long. Classification Calanoida contains the following families, as well as the genus '' Microdisseta'' (which is currently ''incertae sedis''); * Acartiidae * Aetideidae * Arctokonstantinidae * Arietellidae * Augaptilidae * Bathypontiidae * Calanidae * Calocalanidae * Candaciidae * Centropagidae * Clausocalanidae * Diaixidae * Diaptomidae * Discoidae * Epacteriscidae * Eucalanidae * Euchaetidae * Fosshageniidae * Heterorhabdidae * ...

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of 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, and puddles, damp moss, or water-filled recesses ( phytotelmata) of plants 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. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form ...

Euchaetidae
Euchaetidae is a family of marine copepods. The family is cosmopolitan and occurs in all the oceans, including the Southern and Arctic Oceans. Euchaetidae are medium to large-sized copepods. Genera There are two genera with in total 114 species: Ecology ''Euchaeta'' are mostly epipelagic whereas ''Paraeuchaeta'' are mostly bathypelagic. Where more than one species occurs, congeneric species (or life stages of a single species, as observed for ''Paraeuchaeta antarctica'') may partition the water column, whereas species representing different genera that occur at similar depths differ in dietary preferences. ''Paraeuchaeta'' can be important predators of fish larvae. Their mode of predation is " drift and wait". The dominant euchaetid in the Southern Ocean is ''Paraeuchaeta antarctica''. It is a dominant predator there, and its fatty acid profile suggests that it mostly preys upon herbivorous calanid copepods. In the Weddell Sea The Weddell Sea is part of the Southern Ocean ...

Centropagidae
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.
