We have various snakes that are harmless, feral hogs, bobcats, and the very rare Florida Panther. I've lived here all my life and have yet to see one outside captivity. Be careful where you sit, stand, or place your hand. The Brown Recluse is on of many spiders that are toxic. Just remember these creatures only want to be left alone but can be trouble if bothered. You likely won't encounter any of them but they don't mention them in travel brochures.
BIG NOTE: Wherever you are in Florida DON'T feed the seagulls. If you do you will step right into a scene from an Alfred Hitchcock movie!
