Have you ever wished you could stay young forever ? IF you have, you’ll probably be jealous of the Turritopsis Nutricula, a type of jellyfish, for their amazing abilities. These tiny creatures, which consist of almost 99 percent liquid, are practically immortal. What makes this kind of jellyfish so special?
The Turritopsis Nutricula can grow old, but instead of meeting the end of their lifespan, they start to age backwards. These jellyfish are actually stationary polyps from the very beginning. After feeding with plankton the polyp forms a whole colony of polyps, which later produce jellyfish. This process may take years, but once it’s done, the jellyfish start their amazing journey in the water.
After The Turritopsis Nutricula reaches a certain age, can’t find food or is somehow injured, it starts aging backwards. It grows younger via transdifferentiation of the cells until it becomes a single polyp once again. And the process starts all over again.
This immortal species can live forever if they don’t get eaten by other predators. But thanks to their tiny size – they reach a maximum of around 1/5 of an inch in diameter on their bell – they are difficult to spot in the water.
