I recall seeing the same twitching of the meat from a Mako shark my father and his friend were butchering many years ago. Being the mischievous young boy that I was, I grabbed a piece and snuck up behind the wife of my father's friend who was watching the process. She had her hands cupped behind her back. I don't think I've ever seen someone jump so high in fright as she did when that meat twitched in her hands
