Although many different species and/or subspecies of Mytilus have been recognized along the years, they can be grouped in two main types. The California mussel is a large edible mussel, a marine bivalve mollusk in the family Mytilidae. The larva forms into a juvenile which settles and attaches itself using byssal threads after 2 to 4 weeks (Matson 2000). The beaks of the shell are often eroded. However, it is not a legal authority for statutory or regulatory purposes. 2008. University of Washington Press. Reproduction and Development of Marine Invertebrates of the Northern Pacific Coast. Peters JR(1), Granek EF(2). Univ. Allozyme identification of mussels (Bivalvia: Mytilus) on the pacific coast of South America. 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. 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). 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.

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. Shell is a bluish-black color, often with eroded white valves and darker at margins. On California's Northern Channel Islands, archaeological evidence shows that they were harvested continuously for almost 12,000 years.

An analysis of differences in size, growth rate, age at first reproduction, life span, mode of reproduction, niche and habitats between these two species demonstrates that their life history strategies are different in several important ways.
