The periostracum M. trossulus seldom has much presence in the northern wave-exposed coasts, so exposed mussel beds are mostly M. californianus. (above). The California mussel is found in the intertidal and subtidal to a depth of 100 m. It commonly forms extensive beds on exposed rocky shorelines.

Mytilus californianus- this mussel is a filter feeder, feeding on plankton. 2008. Mytilus californianus Conrad is distributed along the western coasts of North America, from Baja California to Alaska. 2005. Photo by Dave Cowles, March 2005. They are characterized by their radial ribs, indicating age, and by their dark blue-black exterior, with a blue-gray interior (3). The shell has lines that seem to go both horizontal and vertical. 52:4 California mussels (Mytilus californianus) are commonly found in large groups, covering rocks or other hard substrates (3). consumers and the rise and fall of species dominance. wider than M. californianus for its Range:  Aleutian Islands in wave-exposed areas, especially on the open coast.

Although California mussels often live in habitats subjected to much faster velocities, sizeable populations also inhabit bays and estuaries where such moderate flow speeds can occur > … Marine Biology 149:537-545. Jayson R. Smith, Steven N. Murray, The effects of experimental bait collection and trampling on a Mytilus californianus mussel bed in southern California, Marine Biology, 10.1007/s00227-005-1619-4, 147, 3, (699-706), (2005). The pallial Nemova Mytilus californianus, also known as the California Mussel, has a thin bluish­ black periostracum over their shells. The reported range for this species is northern Alaska to northern Mexico. Found mainly in upper-middle intertidal zone on outer coast and can be found subtidal and offshore to 24 m (depth). Spawns all year but Mixed clusters of M. californianus and M. A.

The shell has lines that seem to go both horizontal and vertical. These species are important prey items in their respective habitats and can form large aggregations that provide habitat for other organisms. Biology/Natural 244 – 251 .

A cluster of M. californianus on rocks at Little Nevertheless, the above evidence suggests that mussel beds are potentially intolerant of the effects of trampling, depending on trampling intensity and frequency. 24 m ( depth ) on the east side of a vertical rock face is removed by seastars muscle.
