And you thought Jaws was scary...

Scientists at Michigan State University and Florida Keys Community College have confirmed the discovery of the first two-headed bull shark.

The MSU-led study concluded that the shark, found in the Gulf of Mexico in 2011, was a single shark with two heads and not conjoined twins.

"This is certainly one of those interesting and rarely detected phenomena," Michael Wagner, MSU assistant professor of fisheries and wildlife, said in a news release. "It's good that we have this documented as part of the world's natural history, but we'd certainly have to find many more before we could draw any conclusions about what caused this."

The shark was transported to MSU for further inspection after being studied at the marine science department at Florida Keys Community College.
