10 Animals That Can Do Things Humans Absolutely Can’t

4. The Tardigrade: Survivors of the Extreme

Tardigrades—also known as water bears—are microscopic creatures renowned for their resilience. Capable of surviving extreme conditions that would be fatal to most life forms, tardigrades can endure temperatures from near absolute zero to above boiling, withstand intense radiation, and survive the vacuum of space. Their secret lies in a unique protein that protects their cells and DNA from damage. In a state called cryptobiosis, tardigrades can lose almost all their water content and enter a dormant state, rehydrating and reviving when conditions improve. This incredible adaptability has made tardigrades a subject of fascination for scientists exploring the limits of life and the potential for survival beyond Earth. The resilience of these creatures offers deep insights into the possibilities of life in extreme environments, both on our planet and beyond.
