Savion Duncan · Answer 1

The answer is bilateral symmetry and a coelom

Explanation:

Most members of the phylum to which jellyfish belong, Cnidaria, exhibit radial symmetry, including most hydras, corals and sea anemones. Coelom is the body cavity filled with fluid that runs the complete length of vertebrates to divide the body of an organism into inner tube and outer tube. Coelom at embryonic stage, divides the mesoderm into two layers.
