what kind of symmetry do cnidarians have

Cnidarians primarily have radial symmetry. This means their body parts are arranged around a central axis, and they can be divided into similar halves by multiple planes passing through this axis. Some cnidarians exhibit variations like biradial symmetry or even slight asymmetry, but radial symmetry is the most common and characteristic form among them. Their body forms, such as the polyp and medusa, both reflect this radial organization around a central mouth surrounded by tentacles.
