Fish that live in the polar regions use antifreeze proteins that let them cool down to 28 degrees F, but arctic insects that live on land must worry about things getting much much colder; the champ is the Alaskan Upis beetle which can survive an incredible minus 100 degrees F, it uses Xylomannan and that is not a protein, it is a complex sugar.
