Severed Octopus Arms Can Live On Their Own For A REALLY LONG TIME

Have we all heard of Mike The Headless Chicken who managed to defy having his head hacked off and lived for another 18 months? Well, this is the story of the octopus’ severed tentacle as told by BuzzFeed. But this is no ordinary story. Oh no, these are tentacles that continue to be receptive after being chopped off!

Hello. Hi. You're all familiar with the octopus, yes?

EXQUEEEEEZE ME?

UH YEAH. According to Katherine Harmon, who's writing a book on octopi, their "arms can continue reacting to stimuli even after they are no longer connected to the main brain" FOR UP TO AN HOUR.

According to Harmon, who wrote about the wonders of octopi for Scientific American, the ability of the detached tentacle to continue to respond to stimuli could be a sign that octopi have “nociceptors,” which are “neurons that are dedicated to sensing physical danger.”

So in other words, octopus tentacles can continue to flex, move, and respond to the world around them, even when they’re detached from an octopus brain because they feel fear.
