This bizarre-looking creature is a Bull shark foetus, removed from the body of its captured mother recently off La Paz, Mexico, in the Sea of Cortez.
It appears to have just a single eye in the centre of its head, rather like a cyclops.
The image was shown to two shark experts in California, who were skeptical at first, suggesting it might be a hoax.
Shark expert Felipe Galvan, who has actually seen this shark, told Pisces Sportfishing that he had tried unsuccessfully to buy it from the commercial fisherman who caught it. Although he doesn't want to part with the shark, the fisherman has agreed to allow scientists to do some studies on it.
At first it was thought that the "eye" may have been fused nasal cavities, but further tests are still to be carried out. We are told that a scientific paper is currently under review for publication.
