The Balance of Sharks and Rays in the Bay
A few years ago, a massive bull shark was caught in a Chesapeake Bay tributary, creating quite a stir about "Jaws in the Potomac River."
The truth is, however, that sharks are far more likely to be prey than predator when they encounter people.
Overfishing of sharks up and down the East Coast has destabilized the balance of life in the Bay, with cownose rays multiplying -- and eating more oysters -- because there are few sharks left to eat the rays. (Originally aired Oct. 27, 2010)
