Cold iguanas fall from Florida trees

January 7, 2010 (HOLLYWOOD, Fla.) Kamikaze iguanas -- an invasive species -- are falling from the treetops.

The iguanas may look dead- but iguana experts said that when temperatures fall below 40 degrees the animals go into a hibernation. Once it's above 40-degrees, they will come out of it.

Kamikaze iguanas are not native to Florida and the population is blamed on careless pet owners. They are from South America.
