What is a phylum that is characterized by radial symmetry?

A phylum characterized by radial symmetry is Cnidaria. This group includes organisms such as jellyfish, corals, and sea anemones, which exhibit a body plan that is symmetrical around a central axis. Radial symmetry allows these organisms to interact with their environment from all directions, which is advantageous for their feeding and predation strategies. Cnidarians also possess specialized cells called cnidocytes, which they use for capturing prey.
