Although two species of Mytilus occur within this region (M. californianus and M. galloprovincialis) the California mussel, M. californianus is by far the most abundant Mytilus species at all the open coast rocky intertidal sites (Johnson and Geller, 2006). Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Life‐history theory suggests that trade‐offs exist between fitness components, with organisms balancing investment in reproduction against survival and future reproduction. Hines, A.H.

Parts of shell are often eroded. [citation needed] However, mortality in intertidal open coastal environments is often high, resulting from battering from driftwood and other debris, wave pounding, predation, desiccation, and disease. Benthic algae and other primarily freeliving organisms often act as facultative epibionts, colonizing the secondary space afforded by the mussel's large surface area (Paine 1976, … While these mussels are usually edible, care needs to be taken, because during times of red tide in any given locality, California mussels may contain harmful levels of the toxins which can cause paralytic shellfish poisoning. Mytilus californianus specimen collected 2010-01-25 from Goleta Pier with a genomic DNA sample available at the Ocean Genome Legacy biorepository. Spawning habits of the mussel Mytilus californianus with notes on the possible relation to mussel poison. Alkaline conditions were necessary to make the animals responsive to the spawning stimulus provided by the algae. California mussels are found clustered together, often in very large aggregations, on rocks in the upper intertidal zone on the open coast, where they are exposed to the strong action of the surf.
