Caption: Daphnia water fleas swimming in water, seen through a microscope. These are Daphnia magna, one of the largest species, and can reach up to 5mm in length. They are freshwater aquatic crustaceans that swim by beating their antennae, and feed on algae, bacteria and protozoa. Daphnia is a popular model organism in biological research, as its transparent carapace permits easy observation of its organs.
