Two Headed Shark
Two headed sharks are nothing unusual anymore. Scientists believe that the reason for this is the overfishing, which results in a higher chance for a genetic disorder. If a two-headed shark already survives birth, the chances that he will live for more than a few months are very low.
Three Headed Frog
There are not only to headed animals, but even three headed ones. A great example, is “Froggy” the three-headed frog, with six legs. This special mutation was found in a water resort in England and is one of the rarest frog mutations that was found within the last 200 years. Froggy is also very special, as it survived for many years, which is very unusual for genetic mutations.
