Two heads are better than one: MSU researchers discover rare bull shark
The discovery of a two-headed bull shark tops the list as one of MSU’s most recent discoveries.
According to a press release, assistant professor of fisheries and wildlife Michael Wagner confirmed the first discovery of dicephalia in a bull shark, or bull shark with two heads rather than being two conjoined twin sharks.
“This is certainly one of those interesting and rarely detected phenomena,” Wagner said in the 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 originally found in the Gulf of Mexico in April 2011. Wagner made his conclusion with other scientists at the Florida Keys Community College in Key West, Fla. The shark since has been transported to MSU.
He said this is a rather odd case because most animals with deformities die shortly after they are born.
“You’ll see many more cases of two-headed lizards and snakes,” he said. “That’s because those organisms are often bred in captivity, and the breeders are more likely to observe the anomalies.”
