Florida wildlife and weather authorities have issued public advisories after a recent cold weather system caused invasive green iguanas to become temporarily immobilized across parts of the state, a phenomenon commonly referred to as “frozen iguanas.”
According to the Florida Fish and Wildlife Conservation Commission (FWC), green iguanas are a nonnative invasive species in Florida and are highly sensitive to cold temperatures. When temperatures drop into the low 40s Fahrenheit and below, the cold-blooded reptiles can lose mobility and fall from trees, fences, and other elevated surfaces.
The National Weather Service reported that overnight cold conditions affected multiple regions of Florida, prompting safety advisories for residents. Officials warned the public that iguanas appearing lifeless during cold spells are often not dead and may regain movement once temperatures rise.
FWC officials emphasized that residents should avoid handling fallen iguanas, noting potential safety risks if the animals revive suddenly. The agency reiterated that while iguanas are not protected under Florida law, any removal or humane killing must be conducted in accordance with state wildlife regulations.
Authorities also cautioned residents to remain alert for falling debris during cold mornings, as stunned iguanas may drop unexpectedly from trees in residential areas. No injuries or property damage linked to the cold-stunned reptiles have been officially reported.
State agencies noted that the phenomenon is well-documented during Florida cold snaps and does not represent a new or unusual wildlife emergency. Officials have not announced any enforcement actions, emergency declarations, or additional restrictions related to the event.
