Frozen iguanas could start falling out of trees in South Florida due to unusually cold weather, authorities have said.
Meteorologists have warned residents in the Sunshine State to watch out for the fallen reptiles as the low temperatures paralyse the cold-blooded animals.
"This isn't something we usually forecast, but don't be surprised if you see iguanas falling from the trees tonight as lows drop into the 30s and 40s. Brrrr!" National Weather Service Miami tweeted.
The drop in temperature, to between -1C and 4C, is uncommon for Florida, where even in winter it stays above 18C (65F), and could stun the invasive reptiles.
As the temperature rises they will begin to wake up again.

The same thing happened in January last year, when residents took to social media to share pictures of iguanas falling near to their house.
In 2018 a stunned iguana was pictured sprawled feet-up next to a swimming pool.
Iguanas have been in Florida since the 1960s, but their numbers have increased dramatically in recent years and are allowed to be kept as pets in the state.

The males can grow to at least five feet long and weigh nearly 20lb.
Female iguanas can lay nearly 80 eggs a year, and South Florida's warm climate is perfect for the prehistoric-looking animals.
Iguanas are native to Central America, tropical parts of South America and some Caribbean islands.
