Iguanas fell from the sky in Florida last week, but it wasn't a sign of the apocalypse or a plague.

Instead, it just got a little chilly.

Green iguanas aren't native to South Florida, and it's legal to kill them throughout the year,

but controlling the population of large invasive lizards is a problem, which is why wildlife

managers were happy to see a cold front moving in earlier this month. As with most cold-blooded

critters, iguanas enter a state of torpor if the temperature gets too cold.

Tamps dropped into the mid to low 30s during the cold snap.

This was enough to cold stun many of the iguanas living up in the trees and bring them tumbling down to earth.

Biologists with the Florida Fish and Wildlife Conservation Commission were prepared.

They issued an executive order a few days before that allowed Floridians to collect

as many iguanas as they could stuff in a cardboard box or a dog kennel and bring them to designated

drop-off locations. You'd normally need a permit to keep a live iguana, but this executive order

exempted residents from that requirement. After the cold snap ended,

the commission reported that they'd received 5,195 invasive green iguanas, most of which were left

at the sunrise location near Fort Lauderdale. The lizards were either transferred to permit holders and

sold or euthanized. No one knows exactly how many iguanas are in the

Sunshine State, but I've seen estimates as high as 1 million. 5,000 won't do much to curb that
