Tardigrades can survive in extreme environments. For example, they can withstand temperatures from just above absolute zero to well above the boiling point of water (100°C), pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. They can go without food or water for more than 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce. They are not considered extremophilic because they are not adapted to live in these conditions. Their chances of dying increase the longer they are exposed to the extreme environments, whereas extremophiles are organisms that can thrive in a physically or geochemically extreme condition that would be detrimental to most life on Earth.


Just awesome! 😀
