About An Incredible Species That Can Survive The Most Perilous . Environments. Introduction. Tardigrades- amazing creatures. They can survive extreme habitats that would cause humans and other animals to die a very painful death, some of them even beyond Earth. Never more than 0.5 mm long, these creatures did what 6 ft tall humans could never accomplish- they can be brought back to life! As BBC explains, it’s not how these creatures can survive and why, the question is, why have we never evolved to do the same. They can survive space, extreme heat, extreme cold, large amounts of radiation, great amounts of geological pressure, and without water. Turns out, other creatures can do some of these things, but all of them?- doubtful. This ancient species has been able to do what we never could… . Chordata. An Introduction to Vertebrate Animals .
