A manatee. They are hard to spot in the water, and a motorboat driving over it can injure or kill the manatee if the blades are moving fast enough. Because manatees are threatened, Florida laws typically require boats to drive slower in rivers and coastal areas to protect the manatees, should you drive over one with a motorboat.
“And if you look to your left, you can see a manatee grazing near the shore, or as we like to call them, Florida speed bumps… Yeah, I know it’s a dark joke”
