Although many different species and/or subspecies of Mytilus have been recognized along the years, they can be grouped in two main types. Erlandson et al. Feedback | Le manteau est alors orange chez la femelle, blanchâtre chez le mâle. Like other mytilids, the animal is attached to the substrate with a very strong and elastic byssus. On view at the Aquarium in Rocky Shore. Les sexes sont séparés. The fertilized egg cells become trochophoral larvae, 99.9 percent of which are eaten in the course of their four-week development into young mussels. Alkaline conditions were necessary to make the animals responsive to the spawning stimulus provided by the algae. How does the organism mytilus californianus reproduce(is it sexual or asexual, what is it's mating system)? 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.

The intertidal mussel Mytilus californianus aggregates to form dense beds along the western shores of North America. 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.

The presence of Glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase and the transaldolase-transketolase system has been demonstrated in Mytilus californianus by Bennett and Nakada (1968). The change in reserve equals assimilation p_A minus mobilization p_C. They can be baked, boiled, or fried like other mussels, clams, and oysters. As a foundation species, M. californianus beds harbor up to ∼300 associated taxa, filter particulate organic matter from the water column, and serve as … Mytilus californianus. The California mussel prefers the high salinity, low sediment conditions found on open rocky coasts. 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. Anterior end of shell is sharply pointed.
