I have a great PDF file with all of the snakes that live in Florida. Just trying to find a way to convert it to an image so I can post it. There are only 6 snakes that live in FL that are dangerous. Of those, 2 live mostly in south Florida, and one is rarely seen south of the Panhandle. The other 3 all prefer quiet areas with dense vegitation. And also since 2 of those 3 are rattlesnakes, they are pretty easy to spot if you should happen upon one.
The other 12 snake species that live in FL are pretty spread out as well. So the chances are if you do see a snake, it's most likely not dangerous. I'd still stay away, but they are nothing to be afriad of.
Here are 3 that live around WDW that are not dangerous, but very pretty!
Here's a red rat snake.
Here's an indigo snake.
And here's a scarlet kingsnake.
The scarlet kingsnake does look like this venomous snake that lives in South Florida, the coral snake..
But as they say, "Red touch yellow, deadly fellow!"
