While bull sharks are known to go into the Mississippi River fairly commonly, it is unusual for them to get as far upstream as the Ohio River.We do seem to have an unusual number of upstream sharks (more than one kind) in recent years, though.
There was a bull shark captured in Illinois in the Mississippi near St. Louis.However, I don't think that Ohio River shark is a bull shark.It is a dusky smooth hound or smooth dogfish (http://en.wikipedia.org/wiki/Dusky_smooth-hound).That is a small species of shark that cannot survive in fresh water.It is likely that a tourist caught this dogfish in the ocean and then dumped it into the Ohio or a tributary.It is not a bull shark.There are too many locks and dams on the Mississippi for bull sharks to make to Illinois, Lake Michigan, or Minnesota.
Correction, on second look, it's a spiny dogfish.
