    Only on a recent program on the National Geographic Channel did I first come across these creatures. Water bears or tardigrades are tiny invertibrate creatures that are capable of withstanding astonishing extremes of atmospheric conditions by going into a low metabolic state known as cryptobiosis.

    Water bears have been seen to survive at :

    150 C (300 F) - hotter than boiling water
    -200 C (-330F) - liquid nitrogen temps.
    500,000 roentgen radiation dose - 500 roentgens kills an adult human
    high vacuum, electron bombardment, and other crazy conditions
