What phylum of animals has radial symmetry?

Members of the Phylum Cnidaria, which includes simple marine animals such as jellyfish, corals and sea anemones, have radial body symmetry, meaning that their bodies radiate out from a central point. Members of the Phylum Cnidaria tend to be sessile, meaning they live fixed to a certain point and do not move from place to place.

Radial symmetry helps the sessile members of Phylum Cnidaria to feed. Because they do not move around to different places in order to feed, they need to be able to reach food from a fixed position. These animals' radial symmetry allows them to capture food from every direction.
