Sharks in the Mississippi River: Myth or Reality?

Bull sharks have been spotted swimming in the Mississippi River in Illinois due to rising water temperatures and altered salinity levels caused by climate change. Bull sharks have a unique gland that allows them to regulate the salinity in their bodies, making it possible for them to survive in both salt and freshwater. While the chances of encountering a shark in the Mississippi River are low, it is a reminder of the impact of climate change on our environment.
