Here's something you might not know:

There's a species of jellyfish (Turritopsis dohrnii) that is biologically immortal. When it's injured, sick, or old, it can revert its cells back to their youngest form and essentially restart its life cycle — like a butterfly turning back into a caterpillar. It can theoretically do this indefinitely.

Of course, they still get eaten by predators or die from disease, so they're not truly immortal in practice. But biologically, they've found a way to cheat aging.

Want to go deeper on that, or would you prefer something surprising from a totally different field?
