Texas alligators exhibit remarkable resilience as they opt to endure freezing temperatures rather than vacate their ponds. These tenacious creatures possess a special ability known as 'brumation,' enabling them to withstand extremely cold conditions.
A professional python hunter, hired by the Florida Fish and Wildlife Conservation Commission (FWC) Tom Rahill founds a alligator as he searches for Burmese pythons, in Everglades National Park, Florida on August 9, 2022.
Brumate During Freezing Temperatures
The Swamp Park Outdoor Adventure Center in Ocean Isle Beach, North Carolina, shared videos on social media showcasing how alligators adeptly navigate frozen ponds. Temperatures in the Beaumont area plummeted to as low as 17 degrees.
While these cold-blooded creatures thrive in warmer seasons, Interesting Engineering reports that their inability to self-regulate temperature in colder weather sparked curiosity about their survival tactics.
The video captures a compelling scene of an alligator gracefully floating in a pond, almost entirely encased in ice, with only its snout breaking through the frozen surface following a recent cold spell that swept through the city.
George Howard, the General Manager of the park, provided insight into the unique event, revealing that the facility is home to a dozen alligators. He expressed his excitement at the rare occurrence of witnessing the alligators entering the brumation state, underscoring that it had been several years since the last such event.

In one of the videos showcasing a substantial alligator estimated to be around 9-10 feet in length, Howard described the remarkable sight.
He detailed the alligator with closed eyes, only its nostrils protruding from the water (just enough to breathe), as its entire body remained suspended beneath the icy surface, creating a scene he deemed pretty fantastic.
Despite the captivating experience, Howard noted that the alligators didn't maintain the brumation state for an extended period. As weather conditions improved, they seamlessly transitioned back to their regular state, marking the conclusion of this intriguing natural phenomenon.
Alligators' Ability
Unlike warm-blooded animals, alligators can't generate internal heat, making their ability to endure freezing temperatures particularly intriguing. The survival strategy employed by alligators is distinctive, even among other reptiles and crocodilians.
Typically, crocodilians would bask on sun-warmed rocks outside the water to combat the cold. However, alligators exhibit a stubborn resolve, choosing to remain submerged in their habitat regardless of how frigid the conditions become.
The Washington Post reported that alligators possess a unique survival skill known as 'brumation,' a power-saving mode activated during freezing temperatures. In this state, their heart rate and metabolism experience a significant reduction.
To breathe in frozen ponds, alligators exhibit a behavior termed "snorkeling," where they strategically protrude their snouts from the water. While in the brumation phase, alligators enter a partial hibernation mode, maintaining a minimal heart rate of about three beats per minute.
Unlike mammals that undergo deep sleep during hibernation, alligators remain intermittently active, with occasional periods of activity to drink. Remarkably, these reptiles can sustain brumation for approximately four to five months without any adverse effects.
