Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas.
Daphnia pulex is the most common species of water flea. [3] It has a cosmopolitan distribution : the species is found throughout the Americas, Europe, and Australia. [ 4 ] It is a model species , and was the first crustacean to have its genome sequenced.
Daphnia magna is mainly found in the pelagic zone of water bodies, as it feeds primarily on suspended particles in the water column (mainly algae, but also bacteria and detritus). Nevertheless, compared to other species of Daphnia , it is more often found in association with the substrate where it is able to exploit benthic food sources as ...

The Diplostraca or Cladocera, commonly known as water fleas, is a superorder of small, mostly freshwater crustaceans, most of which feed on microscopic chunks of organic matter, though some forms are predatory. [2] Over 1000 species have been recognised so far, with many more undescribed.
The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis.
Daphnia pulicaria is a species of freshwater crustaceans found within the genus of Daphnia, which are often called "water fleas," and they are commonly used as model organisms for scientific research. [1] Like other species of Daphnia, they reproduce via cyclic parthenogenesis. [2]
