Water Flea with eggs - Daphnia pulex - This most common species of water flea belongs to the family Daphiniidae. It has a cosmopolitan distribution in a wide range of aquatic habitats, although it is most closely associated with small, shaded pools and lakes of an oligotrophic nature. (Their range extends across most of the world - Americas, Europe & Australia - in appropriate habitats, most of which offer little by way of nutrients)
