Record low temperatures left cold-stunned green iguanas scattered across South Florida, prompting hundreds of residents to collect the invasive reptiles from yards, sidewalks, and streets. Florida Fish and Wildlife Conservation Commission opened multiple drop-off sites, allowing people to turn in live iguanas without a permit during the cold snap. Officials say the reptiles enter a temporary shutdown near freezing, but warm back up quickly, urging residents to act safely as crews work to manage the surge.
