Scientists have confirmed that the 'Cyclops' bull shark foetus discovered in the body of its mother by a Mexican fisherman is indeed real.

PFK covered the original story back in June. Scientists were skeptical about the shark which appears to have an 'eye' right in the middle of its head and many people thought it was a hoax.

The fisherman refused to give up the preserved remains of the shark, but allowed scientists to do some studies on it.

After examining and X-raying the fish, they have now confirmed that it's authentic, with the single eye being made up of functional optical tissue. However, they think it's unlikely that the baby would have survived outside its mother's womb.

A scientific paper will be published in a few weeks.
