The tropical animals freeze when temperatures drop below 5 degrees Celsius and enter a lethargic state.
Many Florida residents woke up to find cold-stunned iguanas in their backyards and on the side of the road after a cold front swept the sunshine state.
Videos uploaded to social media showed residents carrying the frozen reptiles.
Palm Beach journalist, Frank Cerabino tweeted a picture of a frozen iguana he found by his poolside that quickly went viral.
Local media reported temperatures dropped as low as 5 degrees Celsius in some parts of South Florida on Thursday (January 4).
Iguanas like other reptiles are cold-blooded and depend on the outside atmosphere to keep warm.
When temperatures drop below a certain temperature, the iguana’s blood flow slows down and they become frozen.
The iguanas’ bodies slowly come back to life when the weather gets warmer.
These iguanas were found near a local pond in Lake Worth, Florida.
