Two-headed sharks are mysteriously appearing in our oceans. Why? Lets find out!

Two-headed sharks may sound like they come from a sci-fi novel. But they are actually very real. Scientist say these strange shark anomalies are becoming more common. They have been already found in Indian Ocean, Australia, Mexico Gulf and Florida such as other single sightings worldwide. But fortunately, they are not spreading fast. These freak-mutations are still very rare. For now. The Reason is most of them don't even survive birth due to natural selection. It makes them very hard to study.
So what is causing these weirdo animals?
Over-fishing has already killed devastating 90% of global shark populations. This causes sharks to inbreed, which narrows the gene pool. Consequently, birth defects appear. Other scientists say that two-headed sharks populations aren't getting larger and that it is in fact very natural thing. Others believe that there are simply more scientific journals to report such anomalies.
