Entering the ocean, one becomes part of the food chain. Pay attention to what's going on around you. Chances are no harm will come to you but if you're that worried about your safety then stay on the beach.
Off hand I don't recall hearing of any shark attacks in the Keys tho one is always possible. I went on shark viewing SCUBA dives and they are a big thing in WPB during shark breeding season. Barracudas are a theoretical danger but I have never seen a report of one.
Just use common sense precautions, don't get in the water at low light periods. Dawn or Dusk. That's when many attacks occur when the critters can't see what they are biting.
The most likely hazard is stepping on a spiny sea urchin which will send you to the ER to have the spines extracted. Or worse stepping a sting ray. There are Man-of-war jellyfish occasionally and out on the reefs you will encounter stinging and biting hazards. Wear diving gloves and never stick your hand down a hole least you have a moray encounter.
But in general there are few likely serious dangers.
