Florida iguanas "cold-stunned" by record low temperatures

 A frozen iguana was spotted in Boca Raton, Florida Tuesday, as the coldest air of the season spread across the eastern U.S., setting several low temperatures across the Sunshine State. The phenomenon—known as "cold-stunning"—occurs when temperatures drop into the 40s, and cold-blooded animals like iguanas lose the ability to move their muscles.
