A bull shark fetus, recovered from the Gulf of Mexico by a Florida Keys fisherman in April of 2011 has made international news and has entered the biology textbooks as being the first confirmed case of dicephalia, or having two distinct heads in the species.
LOS ANGELES, CA (Catholic Online) - Studied at the Michigan State University, the shark was confirmed as a single shark with two heads, rather than conjoined twins.
Professor Michael Wagner, the university's assistant professor of fisheries and wildlife and his team used MRIs to discover that the shark had two distinct heads, hearts and stomachs, with the remainder of the body joining together at the back to form a single tail.
"This is certainly one of those interesting and rarely detected phenomena," Wagner said. "It's good that we have this documented as part of the world's natural history."
