Frozen iguanas are falling out of trees in Florida because it’s so cold

HOUSTON – As Florida faces an intense cold snap, complete with freeze warnings and cold-weather advisories, one unique hazard stands out—falling iguanas.

These reptiles, common in South Florida, often sleep in trees. When temperatures plummet, their bodies shut down, causing them to lose their grip and tumble onto streets, cars, pools, and even unsuspecting pedestrians.

This phenomenon isn’t just bizarre—it can also be hazardous. Adult male iguanas can grow up to 5 feet long and weigh as much as 20 pounds. A falling reptile of that size can pose a real risk. As cold-blooded animals, iguanas struggle to regulate their body temperature in frigid weather.

Once the thermometer dips below 50°F, they begin to slow down and become lethargic. At 45°F or lower, they enter a state of cold-stun, appearing lifeless despite still breathing and maintaining basic bodily functions.

This temporary shutdown helps them survive short cold spells. However, if temperatures linger in the 40s for more than eight hours, many iguanas—particularly smaller ones—don’t make it.

Some iguanas have adapted by burrowing deep underground to stay insulated or settling near bodies of water, which retain heat better than the surrounding air.

While some Floridians worry about the safety of these reptiles, others see the cold as an opportunity. Iguanas are considered an invasive species, known for damaging landscapes and displacing native wildlife. For those who view them as a nuisance, the cold weather offers a chance to reclaim their yards from these persistent reptiles.
