From Natural History of Southeast Alaska
California mussel (Mytilus zonarius), but has a thinner shell, lives in calmer, more sedimentation-prone areas, and generally doesn't exceed finger length. As for distinction between this species and exotic species such as M. edulis and M. galloprovincialis, it is essentially impossible. Look out for Paralytic Shellfish Poisoning (PSP) when consuming this tasty bivalve. Especially in calm areas such as harbors and bays, this mussel tends to have threads running between individuals, and the shells may be quite thin and pale.
