The Turritopsis dohrnii, known as the immortal jellyfish, is a tiny, transparent creature capable of biological immortality. Unlike other organisms, when faced with injury, starvation, or aging, it can revert its cells to their earliest form and transform back into a polyp, the earliest stage of its life cycle. This process, known as transdifferentiation, essentially allows the jellyfish to bypass death, making it a fascinating subject of study for scientists researching aging and regeneration.
