SR, I know you must have seen it, the 2 headed shark movie! It was corny but did you know it could really happen!
Behold a real 2 headed bull shark!!!
As if sharks aren't scary enough, here comes the two-headed version. A fisherman found the two-headed bull shark - in this case, a single shark with two heads, rather than a conjoined twin - in the uterus of an adult shark. The shark was brought to the marine science department of Florida Keys Community College and was sent to Michigan State University for further study:
Wagner and his team were able to detail the discovery with magnetic resonance imaging. Without damaging the unique specimen, the MRIs revealed two distinct heads, hearts and stomachs with the remainder of the body joining together in back half of the animal to form a single tail.
