Solution
Many invertebrate animals such as coral, jellyfish, and flatworms do not have blood because they are able to absorb nutrients and move gases and wastes directly to the outside of their bodies. Blood comes in other colors.
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it. They obtain nutrients and oxygen directly from the water that they live .
