Naw snakes don't just roam around down here in Florida. Only wild snakes I usually see are black racers.

Anoles are extremly overabundant down here. Anywhere you walk you see them running everywhere, although they don't really cause problems.

Now gators and iguanas are different. I have seen some 6-7 foot iguanas down here in the wild. Gators are in pretty much any pond area you can see. I had a pond at my old high school which had 2-3 gators in the pond. Gators don't really hurt anything down here unless humans bother them.
