Daphnia magna is a small planktonic crustacean (adult length 1.5–5.0 mm) that belongs to the subclass Phyllopoda. It inhabits a variety of freshwater environments, ranging from acidic swamps to rivers made of snow runoff, and is broadly distributed throughout the Northern Hemisphere and South Africa.
Daphnia are also known to migrate toward or away from the banks of ponds or lakes. Again, the most likely explanation for this behavior is predator avoidance. Certain species of Daphnia, e.g., D. magna, can be observed clinging occasionally to plants or other substrate. Furthermore, they may browse over the surface substrates to pick up small ...

Daphnia magna. Several Daphnia species are considered threatened. The following are listed as vulnerable by IUCN: Daphnia nivalis, Daphnia coronata, Daphnia occidentalis, and Daphnia jollyi. Some species are halophiles, and can be found in hypersaline lake environments, an example of which is the Makgadikgadi Pan.
Daphnia magna is the species normally associated with the name Daphnia by most aquarists. It has been a favourite live food source since the hobby began. D. magna males are 2 mm in length and females are 3-5 mm. They range in colour from a pale yellow to salmon-pink, often this is affected by their food source.
Predation on Daphnia : Daphnia magna are vulnerable to fish predation due to their size and are lacking or severely reduced in lakes with fish (4). The large size of D. magna protects it from small invertebrate predators, although Chaoborous can prey on immature D. magna.
Background information on Daphnia Part 1 - Physical description Daphnia, commonly called water fleas, are a freshwater zooplankton found in ponds and lakes all over the world. Daphnia received the name water flea due to their jerky swimming motions.
Description Daphnia Magna Culture Live Fish Food. Daphnia Magna is the one that most folks are talking about when they say Daphnia culture. It is the basis of a huge range of studies into toxicity, heavy metals, water quality, aquaculture, aquaponics, you name it.
A large species of Daphnia commonly used in aquatic effluent toxicity testing and physiology studies. An obligate algal feeder, D. magna can be successfully cultured using powdered Spirulina as a food source. One Culture is sufficient for a class of 30 students.
