Jellyfish can be found in seas all over the world and they are one of the oldest multi-organ animals, inhabiting our planet for 500 million years. Whenever it is injured or dying, it can turn its cells back into young cells and start anew. And most of the time they die the old-fashioned way too.

The ‘immortal’ jellyfish, Turritopsis dohrnii. To date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. The discovery underscores "our remarkable underestimation of the extent to which the ocean has been reorganized," said Carlton, who also was not involved in the research. Its large stomach is bright red colored. The pair was surprised to discover that, even though the specimens came from all over the globe, all the genes the scientists looked at were identical.

The process that lets the turritopsis remain immortal is called transdifferentiation and it involves one cell converting from one type to another. Imagine this… You’re old, with a hunched back and greying hair. Thus, when the jellyfish reaches maturity, its cells can convert and it becomes a polyp again. "Nobody is looking into that," she said, "and I don't think you're going to find any secrets in these creatures.". This unique approach to hardship may be helping Turritopsis swarms spread throughout the world's oceans, she added. jellyfish Turritopsis dohrniiTo date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. In it, there is an account of the great sage Utnapishtim, who is warned of an imminent flood to be unleashed by wrathful gods.

No turritopsis dohrnii has been observed in a laboratory for an extended period of time, and there is no other way to establish the age of an individual. Maria's work, along with others', show how genetic studies can help to resolve this problem," said Darling, who was not involved in the recent research. Until 2005, there was a clam called Ming the clam who was aged of 507 years. The creatures are likely traveling in the ship's ballast water—water sucked into and pumped out of ships to provide stability. Like all jellyfish, Turritopsis dohrnii begins life as a larva, called a planula, which develops from a fertilized egg.A planula swims at first, then settles on the sea floor and grows into a cylindrical colony of polyps. 2020 National Geographic Partners, LLC. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual. Meanwhile, polyps could be attaching to the hulls. A potentially immortal jellyfish species that can age backward the Benjamin Button of the deep is silently invading oceans, swarm by swarm, a recent study says. Only one animal is known to have this remarkable ability: a species of jellyfish, Turritopsis dohrnii, a uniquely enduring organism, first discovered in the 1880s in the Mediterranean Sea. By studying how exactly the immortal jellyfish's cells do that, he said, scientists may find clues for the struggle against that other silent, rapidly expanding invader. What impact the jellyfish are having on their new ecosystems is still unknown and requires further study, Miglietta said. Yet a marine sponge specimen has been found to be at least 11,000 years old, with some studies suggesting the potential life span of these creatures to be in the hundreds of thousands of years. The oldest female gorilla living today is thought to be 61. Through asexual reproduction, the resulting polyp colony can spawn hundreds of genetically identical jellyfish—near perfect copies of the original adult. You know that your time is near.
