Daphnia
Sign in to saveDaphnia is a genus of small planktonic crustaceans, 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 spp. live in various aquatic environments ranging from acidic swamps to freshwater lakes and ponds.
OverviewAI-generated
Daphnia is a genus of animals within the kingdom Animalia and phylum Arthropoda. It belongs to the class Branchiopoda, order Diplostraca, and family Daphniidae. The taxon was described by O. F. Müller in 1785. Commonly referred to as water fleas, these organisms inhabit marine, brackish, and freshwater environments.
The genus is accepted in taxonomic records. While one source lists the rank as species with the common name Common Water Flea, other authoritative sources classify it as a genus. Daphnia has been documented in countries including Uganda, Germany, Mexico, and the United States. Specimens are held by institutions such as RBINS-SCIENTIFIC HERITAGE, LACM, ECOSUR, and UAM.
Records indicate 52,406 occurrences and 435 specific records, with 93 associated media files. The taxon is not considered extinct. It is referenced by 292 other encyclopedia articles.

Daphnia Les daphnies sont de petits crustacés mesurant de un à quatre millimètres, du genre Daphnia. Elles vivent dans les eaux douces et stagnantes, quelques espèces supportant des conditions légèrement saumâtres. On peut apercevoir leurs organes internes grâce à leur corps translucide. Leur nom populaire de « puce d'eau » donne une bonne idée de leur taille, de leur forme et de leur façon d’évoluer dans l’eau.

Daphnia is a genus of small planktonic crustaceans, 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 spp. live in various aquatic environments ranging from acidic swamps to freshwater lakes and ponds.
The two most commonly found species of Daphnia are D. pulex (small and most common) and D. magna (large). They are often associated with a related genus in the order Cladocera: Moina, which is in the Moinidae group instead of the Daphniidae, and is much smaller than D. pulex (roughly half the maximum length).
