If you're fan of ordering whole fish at restaurants then you probably don't want to watch this video.
Footage has emerged of a "cooked" fish that appears to rise from the dead as it jumps from a restaurant patrons plate.
The diners naturally jump and react at an apparent zombified fish in the video uploaded to Chinese video sharing site Youku.
But according to a scientific report, this strange phenomenon is not uncommon.
Website IFLScience has examined the matter and found that the movement comes from a chemical reaction that stimulates the fish's muscle issues.
"For some time after death, muscle motor neurons within these tissues still have some membrane potential. The fish's brains are very much dead, but most of their tissue is very much alive in these viral videos," the site said.
Charles Graham, a chemistry professor at the University of Virginia, discussed the matter on Discovery News and said that in these cases most of the fish's tissue is in fact still alive.
"Cell metabolites are nearly intact, membrane voltages or potentials that exist in nerve cells are probably still close to intact."
"Even though the brain function is missing, the tissues will still respond to stimuli."
In this case the stimuli was clearly some kind of ingredient such as salt or soy.
