Key Largo, Fla. -
A two-headed bull shark has been caught off the coast of the Florida Keys near Key West by fisherman who have turned the specimen over to scientist.
According to a study conducted by Michael Wagner and published in the 'Journal of Fish Biology', the shark is just one of only a few ever found and scientifically recorded.
The deformity was the result of the embryo splitting into twins, but stopped half way through for unknown reasons.
“Halfway through the process of forming twins, the embryo stopped dividing,” he said.
