Residents of south Florida are on alert for falling reptiles as the temperatures in the region drop.
Reports of iguanas falling from trees have come from several cities in Florida, where temperatures have reached below 10°C (50°F). The cold-blooded reptiles appear to be frozen stiff, or laying on the ground after falling from tree branches. Iguanas, an invasive species in Florida, are unable to self-regulate their temperature, which means their bodily functions slow down when no external source of heat is present, to the point where they go into a state of hibernation.
While the iguanas appear dead, most are actually fine once they warm up.
