Cases of reversed migration patterns are documented when the risk of visual predation during the day is higher at the bottom or in the littoral zones (for example in the presence of fish that hunt within submerged plant‑beds). [4] [16] Daphnia magna, as the smaller D. pulex, is able to switch to a feeding behavior, termed browsing behavior ...

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 magna. According to the World Registry of Marine Species, Cladocera is a synonym of the superorder Diplostraca, which is included in the class Branchiopoda. Both names are currently in use. The superorder forms a monophyletic group of 7 orders, about 24 families, and more than 11,000 species. Many more species remain undescribed.
Daphnia pulex (Cladocera: Daphniidae) These four orders make up a group of small crustaceans commonly called water fleas. Around 620 species have been recognised so far, with many more undescribed. [22] They are ubiquitous in inland aquatic habitats, but rare in the oceans. [11]
Furthermore, D. pulicaria are ecologically important herbivorous zooplankton, which help control algal populations and are a source of food for some fish. [4] D. pulicaria are closely related to Daphnia pulex , and numerous studies have investigated the nature and strength of this relationship because these species can produce Daphnia pulex ...
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 longispina is a planktonic crustacean of the family Daphniidae, a cladoceran freshwater water flea. It is native to Eurasia . D. longispina is similar in size and sometimes confused with the often sympatric D. pulex (a very common species), but much smaller than D. magna . [ 2 ]
