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.
Without a host to provide a blood meal, a flea's life can be as short as a few days. Under ideal conditions of temperature, food supply, and humidity, adult fleas can live for up to a year and a half. [16] Completely developed adult fleas can live for several months without eating, so long as they do not emerge from their puparia. Optimum ...
Daphnia magna is a key species in many lentic habitats.It can be found in lakes and shallow ponds rich in organic matter sediment. [6] Numerous natural predators are known and can lead to plastic phenotypic responses.
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]
The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis.
The feeding mechanism of the members of the family Daphniidae differs from that of the Macrotrichidae in allowing the animals to engage in filter feeding, rather than having to scrape food from a surface.
Moina is a genus of crustaceans within the family Moinidae. [3] [4] The genus was first described by W. Baird in 1850.They are referred to as water fleas, but are related to the much larger Daphnia magna and the larger Daphnia pulex. [5]
