The arrangement of body parts around a central axis, as the rays on a sun or the pieces in a pie, is known as radial symmetry. Animals with radial symmetry only have top and bottom surfaces; they lack front and back surfaces as well as left and right sides.
Radial symmetry refers to the symmetrical arrangement of parts around a central axis, resulting in a circular shape.
Radial symmetry animals belong to the phylum Cnidaria and include jellyfish, sea anemones, and corals.
These animals have a simple body structure, with a mouth at the center and tentacles that extend outward in a circular pattern.
They do not have a distinct head or tail, and their bodies are capable of performing a full 360-degree turn without having to change their orientation.
Radial symmetry animals are mostly found in the ocean and typically have a sedentary lifestyle, feeding on small organisms that they capture with their tentacles.
