Jellyfish have two stages to their lives. Once they have mated the fertilized eggs settle on the sea floor and develop into small, sessile, polyps. Then some time later these polyps will start budding, each bud will turn into a free swimming miniature jellyfish that becomes part of the plankton and then grows bigger to look like the adult.
