Daphnia physiology
WebThe water flea Daphnia magna (Crustacea, Cladocera) is a cyclical parthenogen, which can reproduce both by parthenogenesis and by sexual reproduction. With its ease of handling in the laboratory, several testing methods using D. magna exist for regulatory toxicity testing. ... Daphnia / physiology Endocrine Disruptors / toxicity* Invertebrate ... WebDaphnia magna (common name "water fleas") are tiny freshwater crustaceans. They are filter feeders, and can survive in culture by eating algae, bacteria, or yeast. The body diameter of adult females is about 3–5 mm (Clare, 2002).
