<P> Symmetry has been important historically in the taxonomy of animals ; Georges Cuvier classified animals with radial symmetry in the taxon Radiata ( Zoophytes ) , which is now generally accepted to be a polyphyletic assemblage of different phyla of the Animal kingdom . Most radially symmetric animals are symmetrical about an axis extending from the center of the oral surface , which contains the mouth , to the center of the opposite , aboral , end . Radial symmetry is especially suitable for sessile animals such as the sea anemone , floating animals such as jellyfish , and slow moving organisms such as starfish . Animals in the phyla Cnidaria and Echinodermata are radially symmetric , although many sea anemones and some corals have bilateral symmetry defined by a single structure , the siphonoglyph . </P>
