Which Are the Most Resistant Organisms on
Earth?
Tardigrades
look like segmented worms, with 8 pairs of very primitive feet and
covered by
an exoskeleton.
Tardigrades
can resist temperatures varying between -270°C (-273°C is zero
absolute) and 151°C
(303°F)
- no bacterium is
known to survive in such extreme temperature values, not to mention
such
variation - exposure to X rays 1,000 times higher than values that
would kill
any other creature, space-like vacuum, or pressures 6 times higher than
those
found on the bottom of the deepest ocean (7,000 atmospheres).
Moreover, tardigrades can stay for decades in a latent stage and revive
when
conditions are right. Some tardigrades revived 100 years later from dry
moss
samples in museums when they were exposed to water.
