Everyone wants meat that’s fresh, but my guess is that few would want it to still be moving. That’s the case with these frogs legs, which twitch and jiggle when they come in contact with salt:
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 that the muscles need is something to activate them and they can still contract and relax (until they run out of ATP or something else shuts down the biochemical machinery).
