Ladies and gentlemen, I present to you....
THE TARDIGRADE!!
It is the
greatest thing, living or not, ever!
But wait, there's more! It's not just the cutest, cuddliest microorganism on the planet...
From Wikipedia: "Water bears are able to survive in extreme environments that would kill almost any other animal. They can survive temperatures close to absolute zero, temperatures as high as 151°C (303°F), 1,000 times more radiation than any other animal, nearly a decade without water, and can also survive in a vacuum like that found in space." All of which I double checked myself.
'Tis greatness!
WATER BEAR FOREVER!!
