Hydra - the polyp, anchored with a stalk, tentacles up; and medusa, the jellyfish, swimming free, tentacles down. All cnidarians have both stages, like larva and adult, but they spend more time in one of them and are known as that stage, for example anemones and jellyfish. Anemones have a tiny jellyfish dispersal stage, and jellyfish have a tiny polyp reproduction stage.
