10 Animals That Can Freeze Solid and Survive (-70°C Arctic Masters)

How do animals survive temperatures that would freeze human blood in seconds? In the unforgiving blizzards of the Arctic and the freezing depths of polar oceans, ordinary rules of biology break down. When water freezes, it expands into jagged ice crystals that shred cell membranes — yet these 10 creatures have evolved biological antifreeze, supercooled torpor, and cellular cryoprotection that defy sub-zero death. From a frog that completely stops its heart and turns into solid ice all winter, to a fish with transparent blood and fur so insulating that thermal cameras can't detect it — here are the top 10 most extreme sub-zero survivors on Earth.
