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 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. (Source-ZMEscience)

I realize the article doesn’t go into enough depth on this, but suppose this behavior can be documented well enough to accept as plausible and possible. How does that impact our old belief that death comes to us all?
Death, the great equalizer. Nothing is certain but death and taxes. Death is the great reward, the deep sleep. For ages it has been the one certainty we could all agree on. We may not have the slightest clue what is going on in life, but we cannot deny that at the end of it all, every single living thing dies. Or does it?
Here’s a case where biology suggests a conflict between reality and the perception that every living thing dies. Maybe we’ve been wrong.
Isn’t it amazing that a simple polyp may possess the ability to do something that humans have wanted to be able to do for our entire history. A simple polyp can do something that religion has promised humanity since antiquity but never been able to bring to pass. All the promises, all the rewards, await us after death. We still all die. I think it’s safe to say that every person alive right now will die. But not this polyp.
On the other side of the aisle, how does this impact scientific presumptions? The presumption of death is pretty widespread. This might add a dimension to “life” that we have dismissed as impossible up to now.
Now that we understand how this process works, will we start to find other living things that practice immortality?
