Why Fish Don't Freeze In The Arctic Ocean

Scientists have found special frost pretection proteins in fish blood. These special proteins prevent fish from freezing in the Antarctic Ocean. They recall to them as anti-freeze proteins and say that they work better than your typical household antifreeze. The freezing point for a fish is -0.6 degrees Celcius and the Antarctic Ocean isn't quite that. The protein located within the fishes blood makes the water molecules around it have a long-range effect.

I personally think that this is an extremely good feature of a fish. It is hard for me to believe that any living organism can actually survive and live in such lows temperatures. I think that it is really cool how the protein makes the water molecules react in that sort of way. I would like for scientists to find out and research more about how the protein works the way it does in the fishes blood. I believe that this is interesting and should be further looked into.
