Since 2008, Two-Headed Sharks have been popping up and experts have been trying to figure out the problem.
Though two-headed sharks may sound like something from one of those B-list movie productions, they are real. Even more perplexing is the fact that more of these mutant fish are turning up especially over the last few years.
Scientists cannot pinpoint exactly what’s casing this anomaly but it would be safe to say that the reasons include the direct results of overfishing, genetic mutations, or chemical pollution, etc.
Recent Two-Headed Shark Discoveries
Fishermen off the coast of Florida found a two-headed bull shark fetus.
Another fisherman discovered a two-headed blue shark embryo while fishing in the Indian Ocean in 2008.
Years later, a 2011 study led by Felipe Galván-Magaña detailed the discovery of two-headed sharks from the blue shark species. The specimen were caught in the Gulf of California and around northwestern Mexico.
Galván-Magaña also reported seeing other mutated sharks like a one-eyed ‘cyclops’ shark caught off the coast of Mexico in 2011. This shark had just one functioning eye positioned at the front of its head.
Such conditions can be traced to a congenital abnormality known as ‘cyclopia’ and it occurs in both humans and animals.
More recently, a team of Spanish researchers including Professor Valentín Sans-Coma (University of Malaga) spotted the embryo of an Atlantic Sawtail catshark which had two heads. Actually, this is the first recorded occurrence of two-headed sharks among oviparous shark species (sharks that lay eggs). They later published their findings in the Journal of Fish Biology.
