    From the page: "They're able to return to polyp stage due to a cell change in the external screen (Exumbrella), which allows them to bypass death. As far as scientists have been able to find out, this change renders the hydrozoa virtually immortal."

    FROM THE PAGE: If you're thinking McLeod, you couldn'tbe further from the truth. What you have to do is think small; notmicroscopic, just big enough to see with your naked eye. Turritopsisnutricula is a hydrozoan, and it's considered by scientists to be theonly animal that cheated death.Solitary organisms are (according to current belief) doomed to die, after theycompleted their life cycle. Hydrozoa are a huge class of predatoryanimals that live mostly in saltwater, closely related to jellyfish andcorals. Eggs and sperm from an adult jellyfish (medusa) and they thendevelop into polyp stage. Medusae evolve asexually from polyps.Still, our Turritopsis nutricula (could we call it Joe??) managed to find a way to beat that. What these little folks do is they revert completely to a sexually immature, colonial stage after they reach sexual maturity. They're even cooler than that. When they're young they've got only several tentacles, but at a mature stage, they get to 80-90 of them.They're able to return to polyp stage due to a cell change in theexternal screen (Exumbrella), which allows them to bypass death. As faras scientists have been able to find out, this change renders thehydrozoa virtually immortal.Random Stumble

    Interesting. I guess the next step is some crazy scientists will DNA-decrypt this thing and eventually use the technology on "reborn" organs. And we will be immortal... or some of our organs will be :P
