Two invasive species in particular have caused serious concern: Burmese pythons, and New Yorkers. The New Yorkers have been coming for years, which is weird because pretty much all they do once they get to Florida is bitch about how everything here sucks compared to the earthly paradise that is New York. They continue to root, loudly, for the Jets, the Knicks, the Mets, and the Yankees; they never stop declaring, loudly, that in New York the restaurants are better, the stores are nicer, the people are smarter, the public transportation is free of sharks, etc. The Burmese pythons are less obnoxious, but just as alarming in their own way. These are snakes that started out as pets of Miami residents, until one day these residents stopped smoking crack and said, "Jesus H. Christ! We're living with a giant snake!"
