The Bull Sharks in the Mississippi River Are Turning Into Something Bigger — And Nobody Knows Why

Bull sharks aren't just ocean dwellers — they've been confirmed hundreds of miles up the Mississippi River, far from any salt water. In this video, we dig into how these predators survive in freshwater, why guides and divers are reporting unusually large, thick-bodied sharks, and what a river full of invasive carp might have to do with it. We look at what tagging research has actually found, and separate the documented science from the dockside legend. Is the Mississippi quietly growing something bigger than anyone expected?
