There’s an “Immortal” Jellyfish that Can Revert Back to its Juvenile Form
The Turritopsis dohrnii, commonly known as the “immortal” jellyfish, has a unique ability to revert back to its juvenile form after reaching maturity. This process is known as transdifferentiation, and it allows the jellyfish to essentially start its life cycle over again. When it encounters unfavorable conditions, such as predation, illness, or food scarcity, it can transform its adult cells into specialized cells, effectively reversing its aging. This remarkable biological adaptation has earned it the nickname “immortal” because, in theory, it can continue this cycle indefinitely. While it’s not truly immortal, it is a testament to the incredible adaptability of some creatures in the natural world.
