Zombie meat will freak you out

 

From Andrew Sullivan:

Robert Krulwich explains the above video:

Because this squid was just killed, its muscle cells were still intact and operational. A live squid moves it tentacles by sending an electrical command from its brain to its muscles. The commands say “contract” or “relax.” But since this animal lost its head, its brain can’t send signals. Salt acts as a substitute. Extra sodium (the salt) sends ions to the cell that trigger the cell to open up, creating a cascade of chemical activities that causes the cell to fire, so the muscle twitches.
