My friend has a reptile farm in central Florida and always drives to Miami for international shipments. He has told me that lots of non-native reptiles live in the glades. I think there are three main reasons, it is a good habitat for alot of animals, the glades are very close to a huge international import location, and three people let pets go in the wild, what better place than in the glades. Problem is, they tend to prey on native species.
