All The Reasons You Should Live In Fear Of An Octopus Apocalypse

List RulesVote up the scariest octopus facts that make you fear an aquatic apocalypse.

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.

    An Octopus's Ability To Contort Means There's Nowhere To Hide

    It is nearly impossible to hide from or even trap an octopus. Octopuses are boneless, meaning they can contort their bodies into all sorts of different shapes and sizes. The only hard structure in the body of an octopus is its beak.

    This means an octopus can squeeze through just about any opening, including holes as small as its eye.

    Octopuses Can Walk On Land

    For the most part, octopuses are stuck in the ocean while humans are safe on land, but this is not the full story. The Abdopus octopus of Australia can come to the surface to hunt, even moving from one tidal pool to another as it searches for prey.

    The Abdopus is not the only octopus that people have spotted on dry land, either. Octopuses in aquariums have reportedly snuck out of their tanks at night to feed on fish from other tanks. In 2017, a baffling mystery occurred in Wales involving dozens of octopuses marching out of the ocean night after night, for no discernible reason.

    Perhaps they were practicing for a forthcoming cephalopod incursion.

    Octopuses Can Edit Their RNA

    Most animals evolve through mutations in their DNA, but cephalopods take a different approach. While their genome remains relatively static through generations, they instead use enzymes that allow them to edit their RNA to diversify their proteins and easily adapt. In fact, a study published in the Nucleic Acids Research journal in March 2020 confirmed the "longfin inshore squid are the first known animals that can edit messenger RNA outside the cell nucleus." 

    There is some evidence to suggest this was perhaps a conscious choice somewhere in their evolution. While this means octopuses and other cephalopods evolve more slowly than other animals, it does give them an unsettling level of control over their genetic adaptability that could be a significant advantage in the event of an octopus uprising. Until then, scientists are hoping to use this information to further improve genetic medicine.

    Octopuses Are Deceptively Complex

    Generally speaking, humans like to think of Homo sapiens as the most complex creatures on the planet. We're smart, adaptable, and tend to see ourselves as the top of the proverbial food chain. In some ways, however, octopuses might have instead prevailed over us.

    Humans have an estimated 20,000 protein-coding genes, while octopuses boast a whopping 33,000 - which may explain why they can do things like selectively edit their RNA.
