While bull sharks are commonly found along coastlines, bays, and harbors, they also frequent a most uncommon shark habitatâfreshwater rivers. The species has been spotted 2,500 miles (4,000 kilometers) up the Amazon River in South America and dwell in Lake Nicaragua, a freshwater lake in Central America. Bull sharks have traveled up the Mississippi River as far north as Illinois and are regularly spotted in India's Ganges. Their ability to tolerate freshwater is rooted in salt retention. Sharks must retain salt inside their bodies. Without it, their cells will rupture and cause bloating and death.
