How Do Animals Survive Freezing? | Animal Science for Kids

How do animals survive freezing cold winters? Discover how wood frogs and icefish use natural antifreeze in this educational homeschool STEM audio. Deep beneath the winter snow, a hidden world of master ice chemists is performing one of nature's greatest survival tricks. While sharp ice crystals would normally damage living cells, creatures like the Alaskan wood frog pack their bodies with natural antifreeze syrup made of glucose. Up to seventy percent of the frog's body water turns completely solid, stopping its breath, brain activity, and heartbeat for months until spring warms it back to life from the inside out. Down in the subzero Antarctic oceans, clear-blooded icefish manufacture specialized antifreeze proteins around the clock to keep jagged ice crystals from growing. From heat-generating snow flies crawling across the powder to caterpillars weathering arctic blizzards, these incredible creatures prove that freezing weather is just another puzzle waiting to be solved. Ask in the car afterwards: How does the wood frog use sugar from its liver to survive being frozen like an ice pop? Why does the Antarctic icefish have clear blood instead of red blood like ours?
