 In January 2008, large numbers of iguanas established in Florida dropped from the trees in which they lived, due to uncommonly cold nights that put them in a state of torpor and caused them to lose their grip on the tree branches.Though no specific numbers were provided by local wildlife officials, local media described the phenomenon as a "frozen iguana shower" in which dozens "littered" local bike paths.Upon the return of daytime warmth, many (but not all) of the iguanas "woke up" and resumed their normal activities.
