Tardigrade
The nearly indestructible micro-animal that survives in outer space/Microscopic Life
Tardigrades, or "water bears," are 0.5 mm long and virtually indestructible. They survive temperatures from near absolute zero to 150 C, pressures six times that of the deepest ocean trench, radiation doses hundreds of times the lethal human dose, and the vacuum of space. They do this by entering a desiccated state called a tun, expelling nearly all water from their bodies.
