I’ve seen sharks, adult and baby sharks before when I was in college, but I have never seen a two-headed sharks, neither a baby nor adult one. So when I read a news that a fisherman from Florida caught a two-headed shark fetus, I never hesitated to read and even gotten curious about the said shark.

The said fisherman sent the 2-Headed Shark Fetus to an animal research laboratory and scientists found out, as shown in the image above showing a radiograph of the shark, that it supposed to be a twin or a two-organism shark but failed to completely divide. Hence, if it is just to look at grossly, one could think that it has two heads.
