How does mytilus edulus move?

Mytilus edulis, commonly known as the blue mussel, primarily moves by using its muscular foot, which it extends to anchor itself to surfaces or to create small movements. However, it is largely sessile, meaning it remains fixed in one location, often attached to substrates like rocks or piers. In some cases, they can use their foot to briefly reposition themselves or to escape predators. Overall, their movement is quite limited compared to more mobile marine organisms.
