As temperatures fall across South Florida, so do frozen iguanas from trees

As temperatures fell across South Florida this weekend, so did the iguanas. CBS Miami reports the cold front that dropped temperatures into the 30s and 40s led to cold-stunned iguanas dropping out of trees. 

The invasive species can't handle cold temperatures very well. In general, iguanas begin to get sluggish or lethargic once the temperature drops below 50 degrees Fahrenheit.

Once the temperature drops below 45 degrees Fahrenheit the iguanas go into a dormant or cold-stunned state. They appear to be dead, but they are not. They remain breathing with critical body functions still operating.
