Extraterrestrial animal?

The so-called water bears , Tardigrada, are tiny animals (more than 1000 subspecies of various sizes) that do not exceed half a millimeter in size. However it is not this characteristic that distinguishes them between the immense terrestrial fauna.

These tiny, strange animals are able to withstand and survive a series of circumstancesthat would annihilate any other species, making them the most resistant species in the world. Here are some of his prodigious features:

  • Pressure. They are capable of surviving 6000 atmospheres of pressure. That is, 6000 times more than the pressure that exists on the surface of our planet.
  • Temperature. They are able to “resuscitate” after being frozen at -200º, or withstand positive temperatures up to 150º. In Japan they carried out an experiment in which they revived specimens of Tardigrada after 30 years of freezing.
  • Water. They can survive for up to 10 years without water. Its usual humidity is 85% and can reduce it by up to 3%.
  • Radiation. They are able to withstand radiation 150 times higher than those that would kill a human being.

These prodigious animals have been known since the year 1773. They live on moist surfaces of ferns, mosses and lichens.
