I would be a crow because they can fly and they are intelligent too. I would also like to be a kestrel because they can fly so fast. Flying must be so great...
The Tardigrade is immense. They are more commonly known as water bears. THey can survive anywhere their is water; on the ocean floor, in polar ice caps, in radioactive springs or in a pond. What is amazing about them is that if their water supply dries up so do they. Theor life processes stop they are idle but still alive. In this state they ar almost indestuctable. They have been cooled to -272 degrees c and resurected and warmed to 151 degees c. THey have been stored in liquid helium for a week and given doses of radiation thousands of time the fatal dose for humans. They have been squashed with pressured 6 times greater than the bottom of the ocean. But with a drop of water they spring back to life. Oh I should mention they are a twentieth of an inch long
