The videos show the snouts of several gators poking above the surface of water that appears to have frozen over during the recent winter storm that impacted much of the East Coast.
If they need to breathe, the alligators can poke their nostrils right above the water.
Alligators can regulate their temperature so they can remain frozen in place until the ice melts.
Howard says they lower their body temperature and metabolism under water to survive.
The ice hardened around the gators' snouts with their bodies suspended in the water, said Howard.More news: British PM May to reshuffle cabinet, appoint new ministers

The report also states that the Shallotte River Swamp Park where the video was filmed is a 65-acre sanctuary for "dozens" of rescued alligators in captivity.
"(It's) just an absolute awesome survival technique and these guys were built tough millions of years ago and they remain tough today", Howard said.
Alligators then enter "a state of brumation, like hibernating".
Experts from the Shallotte River Swamp Park explained how it's all possible. Turns out they stick their noses through the ice to survive.
"Just shows you how smart they are, and how unbelievable it is to see them do this exact survival technique, no matter how horrific it looks to us humans", posted Linda McMullan on Facebook. Most are found in the southeastern corner of the state.
