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)

Volvox are green algae that form hollow, spherical colonies of thousands of cells. In some species, individual algae are connected by strands of cytoplasm, and there is division of labor between different groups of cells. Volvox and its relatives have therefore been used as model systems to study the evolution of multicellularity and cellular differentiation.
