The animal that can live forever

It can reverse its own aging!

Did you know that there is a species of jellyfish, so-called “immortal jellyfish”, that can… well… potentially live forever? When faced with unfavorable conditions such as starvation, physical damage, or disease, this jellyfish is capable of reverting back to its juvenile form and starting its life cycle anew, effectively resetting the aging process. While this ability does not make the jellyfish truly immortal, it is still a remarkable feat that has fascinated scientists for years -and that they are studying to understand our own aging.

An immortal jellyfish as supplied by Dall-E-2 and modified by the author.

The “immortal jellyfish”, scientific name Turritopsis dohrnii, is a tiny species of jellyfish that can grow up to just about 5 millimeters in size. It is found in the waters of the Mediterranean Sea, as well as in other parts of the world.

In theory, at least, this jellyfish can live forever.

This unique ability is due to a process known as transdifferentiation: When the jellyfish is exposed to stress or environmental changes, its mature cells can transform into a younger state and then into any other type of cell in the body. Essentially, the jellyfish can reverse the aging process and start its life cycle again.

Scientists have conducted several experiments to better understand the biology of the immortal jellyfish and its remarkable ability to reverse its aging. For example, in one study, researchers used a combination of gene expression analysis and microscopy techniques to identify specific genes and molecular pathways involved in the transdifferentiation process. Other studies have explored the role of stress and environmental cues in triggering the jellyfish's transformation.

The findings from these studies could have important implications for our understanding of aging and age-related diseases. For example, if we could better understand the mechanisms underlying the immortal jellyfish's ability to reset its aging, we may be able to develop new therapies for age-related diseases or even find ways to extend human lifespan:

Note that as I highlighted in a recent article, research on aging has become the focus of major companies and academic labs which are somehow seeking how to “live forever” and to learn how to cure age-related diseases:

No doubt, the immortal jellyfish is a fascinating and mysterious species that continues to intrigue scientists and the general public alike.
