Radial Symmetry in Cnidaria
The phylum characterized by radial symmetry is Cnidaria. In this body plan, the body is arranged around a central axis with multiple identical or similar parts radiating outward. This is seen in jellyfish, sea anemones, and corals.
Cnidarians have gelatinous bodies, radial symmetry, and stinging cells called nematocysts, which they use to capture prey and defend themselves.
