Florida is on alert as plummeting temperatures may cause iguana lizards to fall into the streets.
An arctic air mass could drive temperatures down, causing tree-dwelling iguanas to lose their grip and drop from branches.
As cold-blooded animals, iguanas rely on their environment for body heat, which they cannot generate internally. They typically thrive in hot, humid climates. When temperatures suddenly drop, they experience cold shock, rendering them immobile and causing them to fall from trees.
