The sensing functions include a nerve net, a network of nerve cells that surround the hydra's body. The nerve net enables the hydra to respond to stimuli and coordinate its movements.. Jellies have the medusa body form. Medusas move freely about in the water, transported by wind, water currents, and rhythmic contractions of the "umbrella." Some cnidarian life cycles include both a medusa stage and a polyp stage. Others exist only as medusas. Still others such as hydras and sea anemones exist only as polyps.
