Share. By Jennifer Kennedy. Definition: Radial symmetry is the regular arrangement of body parts around a central axis. When an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.Examples: Sea urchins have radial symmetry.hen an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.
Additionally, two groups of cnidarians, corals and sea anemones, exhibit six-or eight-fold symmetry. These types of symmetry are referred to as hexamerism and octamerism, respectively. It should be noted that cnidarians are not the only animals to exhibit radial symmetry. The echinoderms also display radial symmetry.
