In the video, an alligator is seen sticking its snout out of a frozen swamp.
"It's interesting to see them poke their noses up and are able to breathe and be perfectly fine so they're doing this as a mechanism so that if it freezes over they can still breathe but just an absolute awesome survival technique", Howard said.
Howard says they lower their body temperature and metabolism under water to survive.
Alligators in southeastern North Carolina poke their noses through ice to survive unusual winter chills battering east coast of the United States since last week.
Alligators can hold their breath for up to 24 hours, according to the Swamp Park.
Once warmer weather returns and melts the ice, the alligators will thermoregulate their body temperatures with a spot of sunbathing. Alligators will go into a state of brumation.

"(It's) just an absolute wonderful survival technique and these guys were built tough millions of years ago and they remain tough today", Howard said.
The 65-acre park and sanctuary has a dozen alligators, all of them "rescues" that were previously kept in captivity.
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.
"Obviously, that is not optimal, being frozen like that", he said.
