The immortal jellyfish: A real-life Benjamin Button in the Ocean
Be prepared to be surprised by the way you perceive life. The vast and mysterious depths our oceans contain a creature that is so incredible, it sounds as if its existence was taken straight from a sci-fi novel. It is real. Meet the Turritopsis Dohrnii.
The ability of this tiny miracle to cheat the death has confused scientists, and captured the attention of the general public. It is a candidate for “No Way, That Can’t Be True!” This category contains bizarre facts.
How does it become immortal? What makes it immortal?
Unlike most organisms that follow a linear life cycle from birth to death, Turritopsis dohrnii possesses an astonishing ability known as transdifferentiation. This jellyfish, when faced with stress from the environment, an injury or just reaching its normal adult life span, can switch its cells to a younger developmental stage.
Imagine an old person turning into a child, or a butterfly changing back to a caterpillar. This jellyfish is a good example. The jellyfish transforms from its medusa form (bell-shaped), back to its polyp stage. It then attaches itself to the surface, and begins its new life cycle. The process is theoretically infinitely re-usable, giving it biological immortality.
Discovery of Scientific Importance
The 1990s were the first time that Turritopsis Dohrnii showed its unique abilities. It was originally native to the Mediterranean Sea but has spread worldwide, probably by hitchhiking aboard cargo ships. The remarkable regeneration capabilities of this plant have led to research on a variety of fields.
- Ageing Research: Scientists are studying its cells in order to better understand its cellular “rejuvenation”, hoping to uncover secrets which could be applied to human disease and aging.
- Regenerative Medicine Its cells’ ability to change from one type of specialized cell to another has a great deal of interest in tissue regeneration and repair studies.
- Evolutionary Biology Its presence challenges the conventional understanding of natural selection and life cycles.
The tiny creature with big implications
The immortal jellyfish may not be invulnerable against predators and disease but its ability to reset its clock biologically is unmatched in the animal world. The jellyfish is a testament to life’s incredible variety and inventiveness. It reminds us that we can find even the most bizarre concepts in nature.
Next time you read about an animal that is a defiant of nature, think of Turritopsis Dohrnii, a real-life, immortal jellyfish. It will make you wonder, “No, this can’t possibly be true!”
