A seafood bowl in Hokkaido, Japan contains salmon roe, seaweed, some other things, AND A DANCING SQUID!
The creature isn't hoping his perforce is so moving you'll show him mercy. This dancer is dead!
When you pour soy sauce on the dead squid, the muscles contract in response to signals from neurons, which transmit signals around the body by means of a series of sequential influxes of sodium across the cell membrane into the neuron.
Doesn't that sound delish?
