2 bull sharks swam up Mississippi River
The researchers confirmed those two sightings but besides them, the sighting record in the United States was littered with incomplete reports.
Two bull sharks, which are native to the Gulf of Mexico, made their way up to St. Louis by swimming up the Mississippi River separately in 1937 and 1995, a recent study confirmed.
In the study, published in the Marine and Fishery Sciences, Cincinnati Museum Center paleontologist Ryan Shell and Nicholas Gardner, a librarian at WVU Potomac State College, reviewed hundreds of reports of bull shark sightings on the Mississippi River and compared them to archaeological and paleontological evidence of sharks moving through the river.
