    Most jellyfish live anywhere from two months to a year.  The moon jelly and sea nettle can live for 2-3 years. There is, however, one species that can seemingly live forever! Turritopsis dohrnii, also known as the “immortal jellyfish” has the ability to revert to polyp stage in emergency situations by transforming all of its cells to a younger state, then re-grow back into adulthood. During this polyp stage it is able to spawn hundreds of genetically identical jellyfish that can grow into adulthood with it! Due to this survival technique, the jellyfish could potentially live for an idefinite amount of time.
