Animals have epic freezing strategies. Wood frogs can have 65% of their body water turn to ice, then thaw out in spring like nothing happened. Their hearts stop. Their blood turns to syrup. Then—boing—they hop away.
Meanwhile, you shiver when the thermostat dips below 60°F. Perspective, right? The frog is a frozen superhero; you are just a warm blanket addict.
The Fish That Lives in Ice
Meet the Antarctic toothfish. Its blood contains a natural antifreeze protein that stops ice crystals from forming. It swims happily in waters that would turn your blood into a Popsicle.
Scientists are studying this protein to help preserve organs for transplants. So yes, a fish might one day save your life. You’re welcome.
