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.
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]
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.
Fleas are vectors for viral, bacterial and rickettsial diseases of humans and other animals, as well as of protozoan and helminth parasites. [35] Bacterial diseases carried by fleas include murine or endemic typhus [34]: 124 and bubonic plague. [36] Fleas can transmit Rickettsia typhi, Rickettsia felis, Bartonella henselae, and the myxomatosis ...
Some people think there are insects called sand fleas that bite you. But some experts say the creature that bites you and the sand flea are likely entirely different beasts.
By stage 2 (days 1–2), penetration is complete and the flea has burrowed most of its body into the skin. Only the anus, the copulatory organs, and four rear air holes in fleas called stigmata remain on the outside of the epidermis. The anus will excrete feces that is thought to attract male fleas for mating, described in a later section.
There are more than 2,000 species of tiny (0.04 to 0.15 inches), wingless, blood-sucking fleas that live on the body of the host they infest. Although fleas cannot fly, they have developed ...
The name "water fleas" might come from the typical swimming behavior of Daphnia species which is reminiscent of a series of jumps. The movement of the big second antennae generates an upward movement of the whole animal followed by its sinking (hop and sink).
