God is Absolutely Amazing!


(Red Salamander - found here)
“...The terrestrial species of amphibians must also hibernate by either finding a good location for a hibernacula or creating one. American and Fowler's toads are good diggers and burrow deep into the soil, below the frost line. The large mole salamanders (spotted salamander, Jefferson salamander, blue-spotted salamander, slimy salamander) use burrows of other mammals. Other frogs that can't dig, such as the wood frog and the spring peeper, and smaller salamanders, such as the dusky salamander, red-backed salamander, and the terrestrial stage of the red-spotted newt (red eft) find deep cracks in logs or rocks, or dig down as far as they can in the leaf litter. These locations, however, are not protected from freezing.

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.”
