However, you didnt mention Opah (Lampris) which can maintain all its internal organs at a higher temperature than the surrounding water.

The simple answer is that Nature discovered antifreeze long before humanity ever existed, and Nature’s forms of antifreeze are not poisonous. Polar species of fish, as well as polar invertebrates, have organic antifreeze in their blood and tissues. In fact antifreeze has evolved independently in several classes of organisms including plants and fungi as well as animals.
