Turritopsis dohrnii, commonly referred to as the "immortal jellyfish," is a small, hydrozoan species of jellyfish known for its unique ability to revert its cells to an earlier stage of development, effectively avoiding death from old age. This process, known as transdifferentiation, allows the jellyfish to bypass senescence, making it a subject of intense interest in the fields of aging, regenerative biology, and marine ecology.
