The Blue Mussel (*Mytilus edulis*) is a bivalve mollusk commonly found along the coasts of the North Atlantic Ocean. It has a dark blue to black shell, often with a shiny interior. Blue mussels thrive in intertidal zones, attaching themselves to rocks and other surfaces using strong threads called byssal threads. These mussels are an important part of marine ecosystems, serving as a food source for various predators, including birds and fish. They are also cultivated for human consumption and are rich in protein, vitamins, and minerals, making them a popular seafood choice in many cuisines.
