Meet the Water Bear
Tardigrades are eight-legged micro-animals barely half a millimeter long. Despite their cute appearance, they are the toughest survivors on Earth.
- The Strategy
Extreme Survival
When environments turn deadly, tardigrades don't fight back; they simply stop living. They enter a state of suspended animation called cryptobiosis.
