Most cannot be seen naturally with your eyes without the aid of some contraption such as a microscope, magnifying glass or loupe. Overall, local factors such as productivity, salinity and fish predation pressure, despite being factors likely ultimately related to climate often seem better proximate predictors of cladoceran richness than temperature itself. In addition, widespread centropagid species of Limnocalanus and Osphranticum occur in the Northern Hemisphere. Their common name opossum shrimp stems from the presence of a brood pouch (“marsupium”) in females. The southern species, Diaphanosoma orghidani, found in 2005 likely came from the upper Volga, it numbers about 2000/m3.

Free-living freshwater copepods are typically small-sized forms (0.5–2.0 mm), but some species of Boeckella, Heterocope, Epischura, Limnocalanus, and Hesperodiaptomus can reach lengths over 3 mm. While the vast majority of freshwater copepods are transparent or a pale gray or brown, colors may range from black to red, orange, pink, purple, green and blue. Three other orders (Platycopioida, Misophrioida, and Mormonilloida) are primarily marine free-living species of the benthos or plankton. The monophyly of the Copepoda is generally accepted (Boxshall and Halsey, 2004), together with a sister group relationship with the Mystacocarida (Boxshall and Huys, 1989). Given the high natural abundance, universal presence, and importance in the food web, understanding how chemical substances can impact this important class of animals is central to estuarine and marine ecotoxicology. Copepods are often the most abundant macro-zooplankton in lakes, streams, and oceans throughout the world and can even inhabit wet organic soils. The Cladocera exhibit a striking morphological stasis over millions of years, yet they have overcome significant ecological barriers and they continue to show remarkable plasticity. The name of the class is from the Greek words kope for oar and podos for foot, derived from the coupler, which apparently increases the energetic efficiency of the legs.
