The cnidarian body form specialized for swimming is the medusa. Medusas are typically bell-shaped and have tentacles hanging down, allowing them to pulsate and propel themselves through the water. This form is often associated with the adult stage of jellyfish, which are well-known examples of swimming cnidarians. In contrast, the polyp body form is usually sessile and attached to a substrate.
