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 is so ...

Canthocamptidae
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: *'' Afrocamptus'' Chappuis, 1932 *'' Antarctobiotus'' Chappuis, 1930 *'' Antrocamptus'' Chappuis, 1956 *'' Arcticocamptus'' Chappuis, 1928 *''Attheyella'' Brady, 1880 *'' Australocamptus'' Karanovic, 2004 *'' Boreolimella'' Huys & Thistle, 1989 *'' Bryocamptus'' Chappuis, 1928 *'' Canthocamptus'' Westwood, 1836 *'' Ceuthonectes'' Chappuis, 1923 *'' Cletocamptus'' Schmankevitsch 1875 *'' Delachauxiella'' Brehn & Lunz, 1926 *'' Echinocamptus'' Chappuis, 1929 *'' Elaphoidella'' Chappuis, 1928 *'' Elaphoidellopsis'' Apostolov, 1985 *'' Epactophanoides'' Borutzky, 1966 *'' Ferroniera'' Labbe, 1924 *'' Fibulacamptus'' Hamond, 1988 *'' Glaciella'' Kikuchi, 1994 *'' Gulcamptus'' Miura, 1969 *'' Hemimesochra'' G.

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Harpacticoida
Harpacticoida is an order of copepods, in the subphylum Crustacea. This order comprises 463 genera and about 3,000 species; its members are benthic copepods found throughout the world in the marine environment (most families) and in fresh water (essentially the Ameiridae, Parastenocarididae and the Canthocamptidae). A few of them are planktonic or live in association with other organisms. Harpacticoida represents the second-largest meiofaunal group in marine sediments, after nematodes. In Arctic and Antarctic seas, Harpacticoida are common inhabitants of sea ice. The name Harpacticoida comes from the Greek noun ''harpacticon'' (rapacious predator) and the suffix ''-oid'' (akin to) and means ''reminiscent of a predator'' . Harpacticoids are distinguished from other copepods by the presence of only a very short pair of first antennae. The second pair of antennae are biramous, and the major joint within the body is located between the fourth and fifth body segments. They typicall ...
