Frogs That Freeze! How Wood Frogs Survive Winter's Chill.

Did you know there’s a type of frog that can survive being frozen solid? Yes, you read that right! Some frogs, like the amazing wood frog, have a unique “superpower” that lets them survive through winter in the strangest way: by freezing and thawing like magic!

When winter temperatures drop, wood frogs settle down in piles of leaves or dirt, getting ready for their chilly hibernation. But instead of burrowing deep underground like other animals, these frogs simply freeze right in place! Their heart stops beating, and they stop breathing—almost like they’re in a deep sleep. You might think that being frozen would hurt them, but this is where their special adaptation kicks in.

The wood frog’s body produces a natural substance, like a kind of “antifreeze.” It’s called glucose (similar to sugar!), and it spreads throughout their cells. This special antifreeze keeps ice crystals from forming inside the frog’s cells, which is important because ice crystals can be sharp and damaging. Instead, the ice forms around the cells and between their tissues, protecting the frog’s insides from harm. With their organs and cells safely protected, wood frogs can stay frozen all winter long!

When spring arrives and the weather warms up, the ice inside these frogs starts to melt. Gradually, they “wake up” from their frozen state and go right back to hopping around like nothing ever happened! This incredible adaptation helps wood frogs survive in places with very cold winters, and it makes them one of the coolest (and chilliest) creatures in the animal kingdom!

So, the next time you see a frog, imagine what it would be like to freeze and thaw like the incredible wood frog!
