As temperatures drop in Florida this week, residents may notice an unusual sight: green iguanas falling from trees. Commonly found in Central America, tropical South America and the eastern Caribbean, these non-native reptiles are cold-blooded. As the mercury drops, their internal body temperature also drops, leading to loss of muscle control.
As temperatures drop to 4 or -1 degrees, the iguanas “freeze,” causing them to temporarily fall from trees, according to the Florida Fish and Wildlife Conservation Commission (FWC). Although startling, the iguanas usually recover when temperatures rise.
“Don't be surprised if you find iguanas on the ground under the trees the next morning. Don't pick them up or touch them, they will recover later in the day as temperatures rise,” said meteorologist Eric Stone. according to WFLA news.
Residents have been urged not to panic. Although the reptiles may seem lifeless, it is best to leave them where they are. As soon as temperatures rise, these cold-blooded animals will come back to life and start moving.
Captive iguanas cannot be moved or released to other locations in Florida because they are a non-native species. FWC strongly advises against bringing tranquilized iguanas into homes or vehicles to warm them. Once revived, these animals can become defensive and pose a safety risk. If you encounter a stunned iguana, the FWC advises that it can be killed if necessary.
The FWC outlines several methods for killing non-native reptiles, but any method used must immediately render the animal unconscious. To ensure that the iguana does not regain consciousness, its brain must be destroyed through pithing. This humane method prevents further suffering.
If you've killed an iguana, check your city's regulations before throwing it in the trash to avoid fines. Never throw a dead iguana on roads or in waterways as this can also lead to fines.
