I can survive a decade without eating or drinking. I can live in blistering heat or well beyond freezing cold. I can live in the vacuum of space and the pressures of the deepest oceans. Radiation doesn't bother me, and sometimes I turn into glass. I have sharp dagger-like teeth, but I probably will not bite you. You could say I'm almost a superhero. I am a tardigrade, but you can call me Water Bear.
