Antarctic Cod, properly named Antarctic Toothfish, are sea animals with special adaptations to polar cold water.

The Southern Ocean can remain liquid to about 27 degrees F, or -2 degrees C, based on high mineral content.

At -19 degrees C, water is frozen and contains no life.

From the Toothfish Wikipedia entry:

"The Antarctic toothfish is noteworthy, like most other Antarctic notothenioids, for producing antifreeze glycoproteins. . .. The presence of antifreeze glycroproteins allows [these animals] to thrive in sub-zero waters of the Southern Ocean surrounding Antarctica."
