They attach themselves to rock substrates with adhesive bistle fibers that are strong enough to endure the pounding force of countless waves. Here, I examined the interaction of pH and dislodgement stress on the California mussel, Mytilus californianus. It has a shell length of 20 cm long (Ref. Paola C., Henry S. Carson, Geoffrey S. These dynamic habitats pose a suite of physiological challenges to organisms, ... We addressed these questions in three congeneric mussel species (the ribbed sea mussel Mytilus californianus Conrad and two blue mussels: M. galloprovincialis Lamarck and M. trossulus Gould). They are sessile animals. Levin, 2012. The results can be summarized as follows: 1. transverse Ambrose, and P. Fong. Can move Access supplemental materials and multimedia. M. trossulus has a smoother shell and is often wider than M. californianus for its length. Evaluating the importance of demographic connectivity in a marine metapopulation In this pattern mussels maximized 1.5-2 number of mussels in the general area (which would increase Range and Habitat 8 Range Mytilus californianus are found from Aleutian Islands, Alaska (USA) to southern Baja California (MEX) (Morris 1980).

Within the bathym?trie range of the species (about ?30 m to +4 m; Chan, 1973) the mussels occur at highest density in the middle intertidal zone, at approximately +1.5 m to +3.0 m (Paine, 1974). Mytilus californianus, also known as the California Mussel, has a thin bluish­ black periostracum over their shells.
