Meet the world’s only immortal animal
If you’re thinking McLeod, you couldn’t be further from the truth. What you have to do is think small; not microscopic, just big enough to see with your naked eye. Turritopsis nutricula is a hydrozoan, and it’s considered by scientists to be the only animal that cheated death.
Solitary organisms are (according to current belief) doomed to die, after they completed their life cycle. Hydrozoa are a huge class of predatory animals that live mostly in saltwater, closely related to jellyfish and corals. Eggs and sperm from an adult jellyfish (medusa) and they then develop 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 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.

So they’re kind of like the pheonix? but in the water? what the hell? these things are wwweeeiiirrrrddddddd.
wow thats crazy. i wonder how many are floating around and not dying. thats got to effect the ecosystem somehow right?
they are not immortal. I am pretty sure i could kill one given one, and a shovel.
They aren’t -invincible- but if left alone they would live forever.
Yes… immortal practically means not mortal. Meaning infallible to illnesses and old age, but jeb you are right… they can be killed. But damn! That shit is an extraordinary spectacular creature! Makes sense immortality would have it’s derivation on earth from a simpler sea creature such as this. EXCEllent!
…spies for Cthulhu…
