Cnidaria is a diverse group of simple, aquaticanimals found in marine environments. They are characterized by their distinctive stinging cells called cnidocytes, which they use for capturing prey and for defense. Cnidarians exhibit radial symmetry and have two basic body forms: the polyp and the medusa. This group includes well-known organisms such as jellyfish, sea anemones, and corals.
