Did you know lizards go into a type of hibernation when the temperature drops below around 9 degrees C, all body functions but the heart switches off and blood flow is cut to a minimum. When this happens they lose their grip on the tree branches and drop out of the trees. The lizards, which grow up to five feet long, then lie grey and appear dead until the temperature rises again, at which time they usually revive. The "kamikaze" iguanas have become a common sight as temperatures have dropped almost to freezing. The green iguana, originally from Central and South America, is not native to Florida. It is regarded as one of the most invasive species since it was introduced into the ecosystem, by irresponsible pet owners, in the mid-1990s. It is legal to kill iguanas in Florida but only if it is done humanely. If somebody is looking to trap them, now would be a good time because they're not moving. With temperatures expected to fall even lower, many iguanas may not survive. These are sad F.A.C.T.S.
