A closer look
Wood frogs can survive being completely frozen solid for months at a time, effectively dying and coming back to life when the spring thaw arrives. As the temperature drops, the frog pumps massive amounts of glucose into its cells, acting as a biological antifreeze that prevents deadly ice crystals from tearing its internal organs apart. Its heart completely stops beating, its brain activity flatlines, and it turns into a rigid, amphibian ice cube buried under the leaves. Then, it just thaws out and hops away like nothing happened. Medical science spends billions trying to figure out cryogenic freezing for humans, while a slimy, bug-eating forest creature just casually pauses its own life every winter because migrating south sounds like too much cardio
