Double-headed shark fetus netted by fisherman

while a fisherman was fishing off the coast of the Florida Keys when in one of his nets he caught a two headed shark.He brought it to scientist, who hen said that there are 16 recorded two headed sharks and that it was the only bull ever recorded. I think that this is important because finding out more about the species we have today can help use to produce more and maybe these animals may even have a way to help find a cur for a disease.
