Did you know there is a fish that can survive being completely frozen?
The Arctic cod and some Antarctic fish produce special antifreeze proteins in their blood that prevent ice crystals from forming inside their bodies. This incredible adaptation allows them to live in waters that would freeze most other fish solid.
Scientists study these natural antifreeze systems to better understand survival in extreme environments and even improve medical preservation techniques.
Nature has been solving impossible problems long before humans arrived.
Could you survive in water cold enough to freeze your blood?
