Last week, we saw stories of iguanas falling from trees in Florida because the temperature dropped into the 40s.

The iguanas weren't dead, as people first thought, just frozen because their bodies weren't getting enough heat.  

When they warmed up, the little guys woke back up and scurried away.

Now, a swamp park in Ocean Isle Beach North Carolina released a video after visitors to the park told employees that they were seeing alligators seemingly 'frozen,' in their swamps.

Apparently, people thought the alligators were dead.

They're not.

The people at Shallotte River Swamp Park say, while it may look creepy to us, what the alligators are doing is a completely natural response for them to cold weather.

According to the Miami Herald:

"The alligators seem to instinctively know when the water is about to freeze, experts say. They respond by sticking their nose above the surface at just the right moment, allowing the water to freeze around it.

The alligators then enter “a state of brumation, like hibernating.” Alligators can regulate their body temperature in all sorts of weather, park officials said, and can essentially remain frozen in place until the ice melts."

Here's the video making the rounds.
