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.
Snakes have a radial symmetry, meaning that they are symmetrical when a piece of them is cut. Some of the other animals that have a radial symmetry include starfish and even certain flowers.Jellyfish are also prime examples of organisms with a radial symmetry.These animals are symmetrical from an axis that is located in the center, though this is not always the case.nimals like reptiles and sea creatures are not the only organisms that can have a radial symmetry though; even some viruses have been proven to have a radial symmetry, with coats that are comprised of small protein molecules.
