Snake vs blizzard: Meet the snake that survives extreme cold even after being nearly frozen for hours

When you think of snakes, you probably picture them sliding through warm forests, hiding in damp soil, or sunning themselves on hot rocks. A frozen snake trapped in a blizzard? That sounds like the end of the story. Body stiff, iced over, game done.

Except… not quite.

There’s one snake that refuses to go down that easily. Quiet, unassuming, and wildly underestimated, it has figured out how to cheat winter itself. While most cold-blooded creatures would tap out, this one hits pause, waits it out, and lives to slither another day. Call it nature’s sneakiest survival trick.

Meet the snake that stares winter down and somehow wins.

How did snakes learn to survive the freeze?

The unlikely cold warriors here are garter snakes. Normally, they’re not looking for trouble. When winter rolls in, they do what makes sense - curl up deep inside burrows and rock cracks and slip into brumation, the reptile version of hibernation.

But nature isn’t always kind. When sudden cold snaps hit and there’s nowhere left to hide, evolution steps in with a backup plan. Some garter snakes have developed a short-term tolerance to freezing, just enough to survive the worst of it.

A study published in the Canadian Journal of Zoology found that red-sided garter snakes can endure temperatures as low as −2.5°C, even when nearly 40% of the water in their bodies freezes solid. Yes - freezes.

Even more surprising? Many of them bounce back. After about three hours, they can recover almost fully. Push it past ten hours, though, and the odds drop fast. This isn’t magic. It’s a collection of biological shortcuts built over generations, just enough to buy time until the ice melts.

So… how do they pull this off?

When freezing begins, these snakes don’t fight it. They shut everything down.

Blood circulation stops. Oxygen delivery grinds to a halt. Their metabolism slows to a crawl, conserving energy like someone pausing a video game at the exact right moment. It’s not pretty, but it works.

They also get help from cryoprotectants - small amounts of substances like glucose and taurine that protect cells from ice damage. Unlike frogs, which flood their bodies with sugar, snakes keep things minimal and targeted. Just enough protection, exactly where it’s needed.

The result? Their cells survive the freeze for a few crucial hours.

But let’s be clear, there are limits

This isn’t some superhero-level freeze immunity. Garter snakes can only handle mild subzero temperatures, and only for a short time. Stretch that freeze to 24 hours and survival drops to zero. Too much ice, and there’s no coming back.

Compared to wood frogs, which have more advanced freeze-defence systems, garter snakes are working within tighter reptilian limits. Where they live also matters. Deep underground dens in places like Manitoba protect most populations, but snakes on the edges of these habitats are rolling the dice every winter.

Still, for a creature we assume would never survive the cold, even a few frozen hours is nothing short of incredible. Sometimes, survival isn’t about strength, it’s about knowing exactly when to stop, wait, and let nature do its thing.
