Jellyfish lifespans vary wildly, from just hours or weeks for tiny species to over a year for larger ones, with most living about 12-18 months in the wild, but some, like the "immortal jellyfish" (Turritopsis dohrnii), can theoretically live forever by reverting to their polyp stage when stressed, restarting their life cycle. Factors like species, food, predators, and environmental conditions greatly affect their survival.
