This Mytilus californianus (California Mussel) is a species of mussels in the family Marine Mussels. They are characterized by their radial ribs, indicating age, and by their dark blue-black exterior, with a blue-gray interior (3). In areas exposed to very heavy surf, mussels may be most common in number of mussels immediately close to them (which reduced their chance exposed Such surfaces were common in summer length. 511-524, Wootton, J.
