Iguanas stiffen up in South Florida due to low temperatures

It's so cold in South Florida that iguanas are falling from their perches in suburban trees.

Officials with the National Weather Service in Miami said temperatures dipped below 40 degrees Fahrenheit early Thursday in parts of South Florida. That's chilly enough to immobilize green iguanas common in Miami's suburbs.

Palm Beach Post columnist Frank Cerabino tweeted a photograph of an iguana lying belly-up next to his swimming pool, and WPEC-TV posted images of an iguana on its back on a Palm Beach County road.

Green iguanas are an exotic species in Florida known for eating through landscaping and digging burrows that undermine infrastructure.

They're not the only reptiles stunned by this week's cold snap: Sea turtles also stiffen up when temperatures fall. Wildlife officials said the frigid animals may appear dead, but often are still alive.
