Unexplained Mysteries's video: Marine Biologists Made A Worrying Discovery After 90 Of The World s Sharks Suddenly Disappeared

Marine biologists made a worrying discovery after 90% of the world's sharks suddenly disappeared. Today, we take a look at how 90% of the world's sharks disappeared. Sharks are some of the most notorious survivors on our planet. Their ancestors can be directly traced back hundreds of millions of years, and, according to National Geographic, they have made it through at least four mass extinctions and are older than even the oldest fossil forest. However, as successful as they may be, scientists have discovered that they used to be even more plentiful in the oceans of our planet, and that nineteen million years ago some mysterious event decimated the shark population so drastically that they have never been able to recover.
