However, there’s no need to panic just yet. The shark discovered had not yet been born and was removed from the body of a female bull shark in the Gulf of Mexico.
The weird and extremely rare discovery was x-rayed and found to be a single creature with two heads, as opposed to conjoined twins.
The mutated shark would not have survived for long in the wild, according to marine biology scientists.
“This is certainly one of those interesting and rarely detected phenomena,” said Michael Wagner, Michigan State University’s assistant professor of fisheries and wildlife.
“It’s good that we have this documented as part of the world’s natural history.”
