To be honest: I'm working in a seafood shop now, and I also sell Canadian mussels such as lobsters and water mussels. In fact, a small number of water mussels are similar to those of water mussels, and most of them are mainly white, long and large. Water mussels are short and grayish. Of course, malnutrition is not within the scope. I suggest you go to a seafood store and have a look. It's easier to tell the difference, and then you can eat it once, and you can tell it at a glance next time. ......hehe
