Casu marzu is a Sardinian cheese that contains live maggots. The maggots can jump up to five inches out of the c cheese while you're eating it, so it's a good idea to shield it with your hand to stop them jumping into your eyes.
That's fucking disturbing.
Great white sharks can detect the presence of their own blood at just a few parts per million.
Since they have no natural predators except orcas, against whom they are defenseless, when they smell their blood they flee to another continent.
