All radially symmetrical animals live in the water, Cnidarias are a good example of radial symmetry. Bilateral symmetry means that only one plane can pass through the the center of the organism and divide it into similar left and right sides. Bilateral organisms exhibit cephalization because when there is a front and end to an organism, it is helpful to have sensors in the front to know where to go. Majority of animals are bilateral and they live on both land and water. The Echinodermata is both radial and bilateral symmetric. It is bilaterally symmetric as a larvae but when it turns into an adult it becomes
