You've probably seen a few of those terrifying videos of fish seemingly coming back from the dead and flopping around on a dinner plate. Twitter was horrified when a user from Japan uploaded a video of a tuna fish that had already been cut in half flopping around for a solid two minutes.
The clip was posted to Twitter by Yutaka Suzuki along with the caption: "The vitality of the fish is amazing."
We do have some good news, though. The fish is long dead, and not feeling any pain at all. According to Christie Wilcox of Scientific American, the muscles of a fish that was just killed are so fresh that its neurons are still completely in tact. Add some sodium ions from salt to the exposed muscles and you'll trigger the neurons, which will signal to the muscles to contract. And the very dead fish will continue to flip around until its use the last of its energy stores.
It works with squid, as well.
But that didn't stop Twitter from being any less terrified.
