Radial symmetry is a type of body symmetry where an organism can be divided into similar halves by multiple planes that pass through a central axis. This means that if you were to slice the organism like a pizza, each slice would look the same. Common examples of radial symmetry can be found in many marine animals, such as jellyfish and sea urchins. Organisms with radial symmetry often have a circular shape and are typically found in aquatic environments. This symmetry allows them to interact with their surroundings from all directions, which is beneficial for feeding and movement. Starfish and anemones are other examples of creatures exhibiting this form of symmetry.
