Talk about being cold-blooded. This video shows alligators in Shallotte River Swamp Park, located in Ocean Isle Beach, North Carolina, sticking their snouts through the ice to catch a breath of fresh air. They then stayed suspended in the water for the remainder of the wintry weather, breathing but otherwise motionless as they lowered their metabolism and body temperature.

This method of surviving frigid temps is called brumation, similar to hibernation in mammals. It’s often mistakenly called “suspended animation,” but biologists believe this period of low activity can actually lengthen a reptile’s life, not just pause it. That may be why alligators, for instance, are able to live as long as 50 years.
