With the polar vortex sweeping the Midwest and other parts of the nation, there are some animals like alligators that welcome the freeze.

Crocodiles in North Carolina take in winter by letting their body freeze while allowing their nostrils to hang out in the air.

The survival mechanism is called brumation, where there the reptile hibernates underwater for a few days at a time to lowers its body heat and metabolism. Peep the video after the jump.
