Iguanas and anacondas are sometimes residents of Florida and have been for millennia. They will show up naturally from time to times as weather permits. Pythons, however, are another matter. These, along with exotic fish will do some real damage. Weve got start restricting the pet and animal farm industries.Yah i know, but their damage to water bird eggs is far worse. My brother worked for the EPA, numerous private ecologist, and now is doing a bunch of watershed stuff at USF. I've very aware of the invader species. Were finding 13 foot green anaconda's up here in central FL. But the pythons have been frozen back into the glades. But everything lives there.
We had a case up here of an escaped Siberian tiger. It was lucky that its mate did not get out and it hung around close by. It was eventually caught. Imagine if the two of them got out and started breading in Algonquin Park, just 60 miles away. The weather here is ideal for them and the population of 10,000+ Moose would have kept them well fed and in a breading mood. None of their natural diseases to keep them in check and no real competition for the food. The only natural predator in Algonquin is the wolf. They only rarely take moose and would make a nice snack for a tiger.
