During the brutal winter in Alaska, the wood frog achieves a mind boggling biological miracle. As temperatures drop far below freezing, this tiny amphibian literally turns into a solid block of ice. Its heart stops beating completely, its breathing ceases, and more than sixty percent of its body water freezes solid. To any normal observer, the frog is biologically dead.
However, the wood frog possesses a secret survival weapon. Before freezing, its liver floods its bloodstream with massive amounts of glucose. This sugar acts as a natural antifreeze inside the cells, preventing ice crystals from rupturing vital cell walls. The ice only forms around the outside of the cells, keeping the frog perfectly preserved.
When spring arrives, the frozen frog simply thaws out from the inside out. Its heart magically restarts on its own, and within a few hours, it hops away to find a mate. Scientists study this incredible creature today to improve human organ preservation and cryogenics.
