From your wiki link:

"Tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water. They can survive pressures greater than any found in the deepest ocean trenches and have lived through the vacuum of outer space.

They can survive solar radiation, gamma radiation, ionic radiation— at doses hundreds of times higher than would kill a person. They can go without food or water for nearly 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce."

Well, Civ, this is one the strangest postings. I had no idea these things existed.
