Together the Copepoda and Branchiura comprise over 200 described families; 2,600 genera and over 21,000 described species (both valid and invalid, including senior and junior synonyms). The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Some species feed on microscopic plants or animals; others prey on animals as large as themselves. of copepods with marine invertebrates. 1992. For queries involving invertebrates, contact Amy Benson. George, P.V., and A.M. Nadakal. Males of Sphaeronellopsis monothrix, a parasite of marine ostracods, are among the smallest copepods, attaining lengths of only 0.11 mm. Selgeby, J.H. Adults of this copepod species are yellow to brown colored. (1903). Oikos 27(1): 27-33. The caudal ramus of females, which displays no dorsal ridge in the Great Lakes, is 5–7 times longer than it is wide and exhibits a hair-covered inner surface. Present occurrence of Anguillicola novaezelandiae (Nematoda: Dracunculoidea) in Europe and its development in the intermediate host. Treasurer, J.W. BioScience 54: 919-929. Copepod, (subclass Copepoda), any member of the widely distributed crustacean subclass Copepoda. In addition, it allows for multiple editors to correct and edit data. Interestingly, several planktonic species live at different Sars, G.O. Copepods are small aquatic crustaceans and are one of the most numerous metazoan groups in aquatic communities. Some species are planktonic (drifting in sea waters), some are benthic (living on the ocean floor), 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. Journal of Helminthology 71(3): 241-248. 171, Plates I-CII & suppl. It's hard to see what's in the bottle, but when we put the pods into our tank the fish went nuts! Reed, E.B., and N.E. An account of the Crustacea of Norway, with short descriptions and figures of all the species: IV.

Japanese Journal of Parasitology 32(5): 387-392. Cyclopids from subterranean waters of Abruzzes, Italy. This database was originally housed at the Smithsonian Institution, as the World of Copepods website, which was just a flat file database. Copepods 1100  same water depths at the same times. Lastly, it is suggested copepod species Environmental Biology of Fishes 35(1): 63-74. Females’ antennules consist of 17 segments (Einsle 1989; Hudson et al. Three basic suggestions have arisen to explain this mixing of abundant species. Faafeng, T. Kallqvist, and J.P. Nilssen. I-VI pp. Copepod feeding currents: food capture at low Reynolds number. However, they also serve as intermediate hosts of many animal parasites and even parasites of humans, including the fish tapeworm and guineaworm. depth in the water column as they progress through their life cycle. How are so many species able to survive in the same area, all sharing the same resources without one species out competing the rest? van Overdijk, S.A. Bailey, P.T. Water fleas (genus Cyclops), microscopic freshwater species of the order Cyclopoida, can transmit the guinea worm to humans. 1994a. Most aquarium copepods have a single eye in the middle of their head, but copepods of the genus Corycaeus possess … At present over 53,700 bibliographic entries on copepods are in the database. Canadian Journal of Zoology 73: 1699-1711. Maier, G. 1990a. Unlike most crustaceans, they also lack a carapace—a shieldlike plate over the dorsal, or back, surface. 1991b. one of the most numerous metazoan groups in aquatic communities Copepods & Rotifers (16 oz) – Live Concentrated Zooplankton Blend, Copepod Combo Pack (16 oz) - Zooplankton and Phytoplankton Blend, Rotifer Combo Pack (16 oz) - Zooplankton and Phytoplankton Blend. Copepoda Calanoida. Canadian Journal of Fisheries and Aquatic Sciences 60: 740-756. The graph below presents monthly copepod species anomalies, which show whether more (red bars) or less (blue bars) copepod species than average were present. Elgmork, K., and G. Halvorsen. Mar. To Biological Information System for Marine Life (BISMaL), To Yale Peabody Museum of Natural History (YPM IZ 102069). MacIsaac. 2005. Copepods inhabit a huge range of salinities, from fresh water to hypersaline conditions, and they can be found virtually everywhere there is water; from subterranean caves to pools collected in bromeliad leaves or in damp leaf litter on the ground, from streams, rivers, and lakes to the open ocean and the sediment layers beneath. Biological control of undesirable cyanobacteria in culturally eutrophic lakes. The measurement of niche overlap in 8 carnivorous species of lake-dwelling zooplankton. [Use your web search engines and search on copepod for additional sites.]. Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Most species reproduce sexually, but certain forms also reproduce by parthenogenesis—i.e., the eggs develop into new individuals without being fertilized by the male. Current number of accepted species: 11,137. Ecology 36(4): 739-743. Biol. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. This database will hopefully promote the stability in copepod nomenclature and act as a tool for higher taxonomic revisions and regional monographs and then provide a base link for other online databases that use copepod nomenclature.
