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]
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.
In addition to the direct population ecological effects of predation, the process contributes to phenotypic evolution in contrasting ways; larger D. pulex individuals are more visible to vertebrate predators, but invertebrate predators are unable to handle larger ones. As a result, larger water fleas tend to be found with invertebrate predators ...
Cohen added if fleas are in the cocoon stage, vacuuming will force them to wake up, making it easier to kill. "You use a prescribed medication from your vet, then get to an area they hang out in ...
Their legs are long, the hind pair well adapted for jumping; a flea can jump vertically up to 18 centimetres (7 inches) and horizontally up to 33 cm (13 in), [5] making the flea one of the best jumpers of all known animals (relative to body size), second only to the froghopper. A flea can jump 60 times its length in height and 110 times its ...

The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis.
The article doesn't say what to do about a flea infestation once there is no more animal (e.g., new tenants in an apartment that previously had a flea-infested cat). The Cat Flea link says that fleas cannot be sustained on human blood, but does that mean that without a cat to feed on, the fleas will die? How soon?
