Neither cnidarians nor turbellarians possess a circulatory system. For most large, active animals, this would pose a (fatal) problem. Describe and discuss the features of large active cnidarians ands turbellarians that allow them to respire, nourish their cells, and excrete despite the absence of a conventional circulatory system.
Theory predicts that when both terrestrial and freshwateranimals evolve higher metabolic rates, they can be expected toevolve greater challenges to maintaining water balance. Explainwhy this is so for both terrestrial and freshwater animals.
