Daphnia, a genus of small planktonic crustaceans, are 1â5 millimetres (0.04â0.20 in) in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory [1] swimming style resembles the movements of fleas.he two most readily available species of Daphnia are D. pulex (small and most common) and D. magna (large). They are often associated with a related genus in the order Cladocera: Moina, which is in the Moinidae family instead of Daphniidae and is much smaller than D. pulex (approximately half the maximum length).
