God is Absolutely Amazing!
(Red Salamander - found here) |
So, how does a frog or salamander survive freezing or
below-freezing temperatures? Antifreeze! Once ice crystals start to form on the
skin, the liver is signaled to start converting glycogen to glucose (sugar),
and then floods the blood, carrying the sweet antifreeze to all tissues and
organs. This helps keep the cells from dehydrating and shrinking. The
metabolism slowly drops to nearly nothing. The lungs of the partially frozen
amphibian stop breathing and the heart stops beating. But they don't die! Once
the warm rains of spring arrive, their bodies slowly thaw out and all the
glucose in their systems fuel their annual migration from the forest to the
nearby ponds to breed.”
