This video was shared by several different outlets under a variety of captions, but most referred to as the "zombie chicken "Video:
The video first started circulating on Chinese social media sites like Weibo around June 2019. When the video reached English outlets about a week later, it was often accompanied by jokes about" zombie chicken. "However, when Hong Kong News covered this video on June 17, reporters identified the animal as a recently skinned frog. An early posting from the laugh, no worries Facebook page also identified this "zombie" meat as a frog.
These sources do not appear to have any first-hand knowledge of the incident, however, so we should take their claims with a grain of salt too.
Speaking of salt … This video shows an extremely fresh cut of meat. While this animal is certainly dead, its neurons are still active and seem to be reacting to sodium ion, a chemical compound that can be found in soy sauce.
When the Scientific American looked into a similar video back in 201
When a creature dies, its neurons do not stop working right away. So long as there is still enough energy around to maintain that membrane potential, the neurons will work.
What you might have noticed is that in the case of dancing dead, the cooks have added one key ingredient: salt (soy sauce is very salty). Salt – or sodium chloride – is full of sodium ions. This overwhelming dose of sodium ions is enough to trigger the still-working neurons into firing, signaling the muscles to contract.
Scientific American was commenting on the following video from 2009. While the reaction in this footage is not as severe, it
An article from Brain Stuff further explains why these dead animals appear to "dance" when salted:
As you can see, the chef is preparing the frog legs for dinner. He has skinned the frog legs and they are ready to be cooked. When they solve them, the muscles start twitching. The obvious question: Why does that happen?
Because these are fresh frog legs, the cells inside them are all still intact. The biochemical machinery still functions. There is still a source of energy for the muscles in the form of unused ATP molecules stored in the cells. All of the muscles need something to activate and they can still contract and relax (until they run out of ATP or something else shuts down the biochemical machinery) …
In a living frog, it's a nervous signal from the brain that tells the muscle to contract.
While we were unable to track down the exact origin of this video, this footage was probably filmed at a restaurant that practices the ikizukuri, which is a method of preparing live seafood . This method of preparation is most commonly used with fish but octopus, shrimp, lobster, and frogs can also be prepared this way.
In 2012, a restaurant in Tokyo found itself in the path of protesters after a video showing the making of a live frog sashimi dish went viral. Here's how Fox News described that video (which can be seen here):
In the video, a large frog is stabbed, skinned, gutted and served on an iced plate with a lemon slice and soy sauce. Although the frog is killed instantly by the chef's knife, it takes a few agonizing minutes for the frog to stop moving. In those moments, you see the creature's eyes blinking back at the camera while the maudlin music plays in the background, and at points the frog flails its arms and flops around on the dish while its heart is still beating
Although we can
zombie chicken "" zombie frog "video, it certainly falls within the realm of plausibility.
