When you're a Turritopsis nutricula, it's easy to savor life and laugh at your mistakes. After all, you have immortality at your side.

Turritopsis nutricula is a type of jellyfish that uses transdifferentiation to replenish cells after sexual reproduction. It repairs damaged cells and can regenerate itself indefinitely. This makes it biologically immortal!

Imagine beating up your enemy and he or she just keeps healing his or her wounds. Then instead of getting old, he or she can simply go back to his youthful look. That's the ability of this sea creature.

Also, you might want to look at your lobsters in a different light. They are biologically immortal too you know.
