6 facts
These microscopic "water bears" can enter a state of suspended animation, shedding up to 97% of their water. This allows them to endure temperatures from -272°C to 150°C, intense pressure, and radiation doses 1,000 times higher than humans can withstand.
These apex predators have incredibly slow metabolisms, allowing them to conserve energy efficiently. They can enter a state of torpor, drastically reducing their bodily functions and surviving extended periods without sustenance, especially in times of drought, showcasing extreme resilience.
Cockroaches can survive for an extended period without their heads because they breathe through spiracles on their bodies, and their blood pressure isn't dependent on a single major organ like a human heart. They ultimately die from starvation or dehydration.
Snails can enter a state of aestivation, similar to hibernation, to survive unfavorable conditions like drought or extreme cold. During this time, they seal themselves in their shells to conserve moisture and energy, patiently waiting for better times.
Certain frog species, like the wood frog, can survive having up to 65% of their body water freeze into ice. They produce a natural antifreeze (glucose) that protects their cells, allowing them to thaw out and hop away when spring arrives.
These microscopic "water bears" can endure extreme conditions, including the vacuum of space, intense radiation, and temperatures from -272°C to 150°C. They do this by entering a state of suspended animation, making them Earth's most resilient creatures.
