I read an article today that I found quite suprising. It said that because of cold weather, the tree-dwelling iguana's in the southern parts of Florida are freezing stiff and falling out of the trees. Iguana's apparently need a temperature of at least 23 degrees, but last week the temperature dropped down to 4. Under these circumstances the iguana becomes paralysed, only his heart remains active, untill he warms up and 'defrosts'.

The tropical iguanas in South Florida aren't native species, but are released pets which originally come from South-America
Locals see them as pests because they are eating away at the native vegetation of Florida and are seen to be taking over the area.
