This site provides general information about zooplankton, a complex assemblage of microscopic animals in the water column of lakes, ponds, rivers, estuaries and the open ocean.
Causal Agent: Dracunculiasis (guinea worm disease) is caused by the nematode (roundworm) Dracunculus medinensis. Plankton is composed of the phytoplankton (“the plants of the sea”) and zooplankton (zoh-plankton) which are typically the tiny animals found near the surface in aquatic environments. is around 1.2–1.3 mm in length (Torke 2001); females 1.1–1.5 mm, males 1.0–1.5 mm.
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. Names . Common name: a copepod. Journal of Crustacean Biology 10:528-536. The copepod goes through five additonal [sic] molts, with increasing numbers of swimming legs, urosomal segments, and sexual differentiation. Taxonomy: available through www.itis.gov. Life Cycle: Humans become infected by drinking unfiltered water containing copepods (small crustaceans) which are infected with larvae of D. medinensis.Following ingestion, the copepods die and release the larvae, which penetrate the host stomach and intestinal …
2) (cf. Identification: Eurytemora affinis. Like phytoplankton, zooplankton are usually weak swimmers and usually just drift along with the currents. Copepods are generally small, about one to two millimeters (0.04 to 0.08 inches), although the parasitic Pennella sp., the largest copepod in the world, grows to nearly 0.3 meters (Birtles and Arnold 2002).
Journal of Marine Systems 15:23-34. Scientific Name: Diaptomus pribilofensis. Possible aliases, alternative names and misspellings for Diaptomus pribilofensis. Observed in County(s) Clark. Copepod definition, any of numerous tiny marine or freshwater crustaceans of the order (or subclass) Copepoda, lacking compound eyes or a carapace and usually having six pairs of limbs on the thorax, some abundant in plankton and others parasitic on fish. In the latter case, you are looking at a female with two bags of eggs. Welcome to the zooplankton ecology web site in the Program for Fisheries and Aquatic Sciences at the University of Florida.

Common Name(s): A Copepod.
The sixth (CVI) stage is the male or female adult (Uye and Onbe 1975; Barnes 1983).” “Pseudodiaptomus inopinus, like many other copepods of its genus, is characteristic of estuaries Copepod reproductive strategies: Life-history theory, phylogenetic pattern and invasion of inland waters. Phylogenetic analysis of copepod orders.
Common Name: A Copepod. When viewed laterally, the maxillipeds are shorter than the width of the body.
This copepod exhibits a caudal ramus that is more than 3 times as long as wide and has 5 obvious setae. To the naked eye it looks like one or three colored blobs. The Copepoda possess at most six naupliar stages, with stage reductions primarily in non-feeding, mostly parasitic taxa (Fig. No children of A Copepod (Diaptomus pribilofensis) found.
Ho, J.-S. 1990. Calanoida is the scientific name for a copepod, all zooplankton are in the family heterotrophic plankton.
Characteristics: The body length is usually no more than 1-2 mm.
