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.
The first type is radial symmetry. With this type of symmetry, the body plan is based around an axis. In other words, the body is oriented so that is radiates out from an imaginary line through the center of the organism.These organisms have a top and bottom, but they don't have a left and right side or a front and back side. A couple examples of radial symmetry are starfish, jellyfish, and sea anemones.n other words, the body is oriented so that is radiates out from an imaginary line through the center of the organism.
