There are a lot of different creatures living in the Chesapeake Bay, but you wouldn't necessarily expect to see a shark in there.

The Chesapeake Bay Foundation posted these pictures to its Facebook page. The Foundation suspects that it could be a bull shark, one of the most common shark species to visit the bay.
Sharks have visited the bay before, but there have never been any reported shark attacks there. Read more about the most common sharks to visit.
