Sure, we've all heard a lot about the zombie apocalypse by now. People seem to love thinking about how they might fare in the event of exanimated beings coming back to life. Bookstores are full of zombie survival guides, and the Centers for Disease Control and Prevention (CDC) even published guidelines for what to do in case of a zombie outbreak.
As it turns out, however, we may be preparing for the wrong scenario. Instead of spending so much time worrying about zombies, we should be more concerned with the potential of an octopus uprising. After all, as far as we know, zombies don't exist (yet), but octopus facts tell us the sea creatures are evolving every day. And they can be freaking scary - in fact, we have reasons to think that octopuses might be alien life-forms living in our oceans.
Zombies have remained the talk of the town for a while, but we should be keeping a wary eye on our seas instead of graveyards. The octopus apocalypse might be far scarier than any zombie revolution.
