    • Abstract


      Experiments were conducted withAnisops bouvieri as predator to study the advantages of helmet development in cyclomorphic formDaphnia cephalata King and the results were compared with another non-helmetedDaphnia similis Claus. The helmetedDaphnia cephalata avoidedAnisops bouvieri predation better than the non-helmeted formDaphnia similis. The predator selectively preys upon smaller sizedDaphnia similis than the largerDaphnia cephalata.
