Detailed explanation-1: -Radial Symmetry: A radial animal has a top and a bottom (or an oral and aboral side), but has no head end or rear end and no left or right. Examples of animals possessing radial symmetry are: jellyfishes, corals, anemones, and ctenophora.
Detailed explanation-2: -Radially symmetrical animals have top and bottom surfaces, but no left and right sides, or front and back. The two halves of a radially symmetrical animal may be described as the side with a mouth (“oral side”) and the side without a mouth (“aboral side”).
Detailed explanation-3: -Because of the circular arrangement of their parts, radially symmetrical animals do not have distinct front or back ends. They may have distinct top and bottom sides. Some examples of these animals are jellyfish, sea urchins, corals, and sea anemones.
Detailed explanation-4: -Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.
Detailed explanation-5: -In animals, bilateral symmetry is always associated with the B. development of a head. Animals with bilateral symmetry often have an anterior head, a posterior tail, a top, a bottom, as well as a right and a left side. Bilateral symmetry is also often accompanied by a well-developed brain and nervous system.
