While many of us wrap up warm, stay indoors and avoid the cold winters, the same cannot be said for the wood frog. The reptile is blessed with a type of blood which lets it naturally freeze with it’s surroundings and thaw out when the weather begins to warm up. Rather than migrate to warmer climates or dig a burrow underground, the wood frog simply rests under leaves and naturally freezes with the weather. While it’s skin freezes solid, its special blood allows the frog’s organs to keep on functioning and literally be frozen alive. That’s one way to avoid the cold winters!
