Several years ago, I had a dinner party and decided to cook up some really yummy marinated mussels for the entree. The 4 of use sat down and started eating the mussels, crunch after crunch, then my guest decided to look closely at what was so crunchy, nearly every mussel has little crabs inside of them. They too were marinated. It turned me off eating any more that evening. Now whenever I eat or cook mussels I investigate them thoroughly. (two for the price of one really)
