This jellyfish is immortal: it can live forever
Humanity has been searching for immortality for millennia. But there are living beings that are already biologically immortal. For example, certain species of jellyfish.
We believe we are the most evolved species on Earth, but in certain respects, there are others that surpass us. There are jellyfish that are immortal. They could live forever in the absence of predators or disease.
Humans spend hundreds of billions a year on anti-aging creams, medications, healthy food, or the gym. We become obsessed with living longer, and thanks to science, we are succeeding: in just a couple of centuries we have doubled life expectancy. But we’re still a long way from the immortal jellyfish: the Turritopsis nutricula, the Turritopsis dohrnii, and others.
These jellyfish or hydrozoans have ability to return to childhood as adults, to start their life cycle anew and live forever. You can see the Turritopsis dohrnii jellyfish in this video:
How is it possible that these jellyfish are immortal? Is due to a unique cellular process called transdifferentiation.
This process allows the jellyfish to return to the polyp state, that is, to a young jellyfish, even when it is already in maturity and has already reproduced.
From its polyp state it returns to develop and reproduce. They have the ability to repeat the cycle indefinitely, so it is about biologically immortal animals.
Regression to the polyp phase is available at any point in its life cycle, not just at maturity. Sometimes it happens when they feel threatened, or when they get sick.
If these jellyfish are immortal … why haven’t they ended up colonizing the entire sea? Although they can live forever, they are still subjected to the dangers of Nature, and most they die from disease, predators, storms, pollution, changes in water temperature, etc.
Scientists have been studying the cells of the Turritopsis nutricula and the Turritopsis dohrnii, looking for clues that allow apply this rejuvenation cellular to humans.
Perhaps not to go back to childhood or adolescence, but to heal damaged organs or parts of the body, or to apply in cosmetic products.
