It begins like the life of almost any jellyfish: a tiny larva, a drifting creature, a growing adult. But when the immortal jellyfish reaches the end of its life—or is badly injured—it can do something that seems impossible. Instead of dying, it can transform its adult body back into an earlier stage of its life cycle and begin again.

In this episode of Animal Uncovered, we follow the extraordinary life cycle of Turritopsis dohrnii, from microscopic beginnings to mature jellyfish and the remarkable biological process that earned it the name “immortal.” But is it truly immortal? And what does this strange creature reveal about aging, regeneration, and the limits of life itself?
