context_page_description: Daphnia magna is a small planktonic crustacean 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.
  The species has been subject of biological research since the 18th century. It is widely used in ecological and evolutionary studies, and in ecotoxicology. It is a popular fish food in aquaculture and aquaria.
context_section_description: D. magna has become a model system to study the evolution and ecology of host-parasite interaction. Animals collected from natural habitats are frequently infected. Many parasites that infect D. magna have been identified and studied (Table 1), D. magna shows parasite-induced behavioural characteristics that can differ among genotypes.
