- Explain why some animals do not require a circulatory system.What is a characteristic of the circulatory systems of arthropods and mollusks that distinguishes them from the circulatory system of echinoderms? They have lungs. They have muscular pumps to circulate the extracellular fluid. They are closed circulatory systems. They have extracellular fluid to transport substances to and from internal organs. They have cilia to circulate the extracellular fluid.What is the type of circulatory system present in arthropods? Do these animals have heart and respiratory pigments?
