Daphnia magna is widespread in the Northern Hemisphere and in particular in the holarctic. [2] It can be found in fresh and brackish water bodies of different sizes, from lakes to ponds and ephemeral rock pools near the sea. D. magna tolerates higher levels of salinity (up to one-fifth the salinity of sea water) than most other species of the ...

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 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.
A round leaf where the petiole attaches near the center, e.g. a lotus leaf perfoliate: perfoliatus: stem attachment: With the leaf blade surrounding the stem such that the stem appears to pass through the leaf perforate: perforatus: leaf surface features Many holes, or perforations, on leaf surface. Compare with fenestrate. pinnately lobed ...
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 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]
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]
