Florida is being overrun by Nile monitor lizards (Varanus niloticus), according to this story at TBO.com News. How is it that Cape Coral is filled with hundreds, possibly thousands of these poisonous African reptiles? They either escaped or were let loose from people who kept them as pets. This article from News-Press.com has more details about the lizard situation and contact info, in case you spot a monitor lizard in the wild or want to help with a proposed research/eradication program.
