6 Animals That Freeze and Come Back to Life (Explained in 8 minutes)

A frog that turns itself into a block of ice — on purpose. A microscopic animal that laughs at liquid nitrogen and survives in the vacuum of outer space. A caterpillar that freezes solid fourteen winters in a row just to become a butterfly for a few weeks. And an iguana that literally falls out of a tree when it gets cold… and walks it off like nothing happened. These aren't science fiction. These are real animals doing things that shouldn't be biologically possible — and scientists are still trying to figure out how. In this video, we break down 6 animals that freeze and come back to life, the wild survival mechanisms behind each one, and why researchers studying them might one day change human medicine forever. #curious #animals #nature #didyouknow #sciencefacts
