Some basic info on Zooplankton Daphnia: Freshwater zooplankton Daphnia (or Daphnids) are members of a collection of animals that are broadly termed as “water fleas”. These are predominantly small crustaceans, and Daphnia belongs to a group known as the Daphniidae (which in turn is part of the Cladocera, relatives of the freshwater shrimp, Gammarus et al, and the brine shrimp, Artemia spp). They get their common name from their jerky movement through the water.
