T. dohrnii.
The immortal jellyfish, as T. dohrnii has been dubbed, doesn’t exactly live on forever sans aging — in fact, in the face of any external threat, it undergoes a reverse-aging process and transforms into an infantile (the jellyfish version of it) state. Going back to a jellyfish’s origins may help put this into perspective: essentially, a ...
When the medusa the immortal jellyfish ( Turritopsis dohrnii) dies, it sinks to the ocean floor and begins to decay. Amazingly, its cells then reaggregate, not into a new medusa, but …Research on T. dohrnii and Hydra polyps provides irrefutable evidence of the importance of stem cells in longevity. And last but not least, experiments on such specific organism like Hydra provide a unique opportunity to make direct genetic and functional comparisons between non-aging and induced aging organisms.Sep 14, 2021 ...

If the environment gets too harsh or Turritopsis dohrnii gets injured, it can melt its body into an amorphous cyst, reattach to the ...
T. dohrnii is believed to have first appeared in the Pacific, but it has now spread across the world and branched into several populations of genetically identical jellyfish. It is unlikely that the Jellyfish’s spread was caused by ocean currents, as the cysts from which it regenerates are found at much lower depths.Turritopsis dohrnii, la méduse immortelle, est une espèce de petite méduse, d'environ 1 cm de diamètre, qui est biologiquement immortelle [1], [2].Cet hydrozoaire se retrouve en Méditerranée et dans la plupart des océans du globe .
