Bull shark caught in Alton, IL in 1937.
Sharks In Illinois ~ According to the Illinois Department of Conservation, in 1937 two commercial fishermen from Alton, Herbert Cope and Dudge Collins, caught a 5-ft, 84-lb bull shark in the Ohio River. It was displayed at the Calhoun Fish Market. Biologists later concluded from the photos that it was a bull shark, which can live in fresh water. From the Gulf at New Orleans up the Mississippi River to Alton is about 1,750 miles. Dams now prevent sharks from entering Illinois.
