The cold temperatures have caused the pond they live in to freeze over. Once it becomes warm and the ice melts, the creatures will thermoregulate their body temperatures to their regular state.
Alligators have a unique way of surviving cold weather - and a video captured exactly how they do it.
When the water or air temperature falls too low for them to be active, Howard says alligators go into a hibernation-type state called brumation. Alive or not, seeing a motionless alligator's snout popping out of a frozen over pond looks more like a scene out of a B-grade horror film than a natural occurrence.
"(It's) just an absolute incredible survival technique and these guys were built tough millions of years ago and they remain tough today", Howard said.
All of the alligators in the park have been rescued from captivity and therefore can not go back to the wild.
The video clip has awed commenters on social media, prompting people to pepper Shallotte River Swamp Park with concerns about whether the alligators are dead and questions about what happens if someone steps on a frozen alligator by accident.
Now you know. See ya later, alligator!
A Carolina Coastal Review study suggested the farthest west they might appear would be Richmond County, though none have been recorded living naturally past eastern Scotland County. Experts said they believed the alligators may have been pets released by their former owners.
