Radial symmetry is a type of 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 organisms with radial symmetry include jellyfish, starfish, and sea urchins. In nature, radial symmetry is often found in aquatic animals, as it allows them to interact with their environment from all directions. This form of symmetry can help with feeding, movement, and reproduction, making it an effective adaptation for survival in their habitats.
