Identification Guide
California mussels (Mytilus californianus) are unique marine creatures with distinct features that help in their identification. Recognizing their characteristics can be useful for anyone studying these animals or exploring coastal habitats.How to Identify a California Mussel
To identify a California mussel, one should look for its elongated, oval shape, typically measuring between 5.1 to 9.9 inches in length. The shell color is usually bluish-black on the exterior. When inspecting closely, fine radial ribs are often visible. The interior of the shell showcases a bluish-grey tint, sometimes displaying iridescent patches. These mussels usually cluster on rocky surfaces in the intertidal zone. Examining the size and growth patterns can also be helpful, as California mussels reach their full size after approximately three years.Characteristics
California mussels have several distinctive characteristics. Their shells are thick and can display noticeable erosion due to environmental factors. The shell structure typically includes strong radial ribs that run perpendicular to the natural growth lines. The periostracum, a coating on the outside of the shell, contributes to its bluish-black color. Inside the shell, the smooth and shiny surface can be outlined with shades of grey and hints of color. These factors are key identifiers when observing these animals in their natural habitat.Comparison to Similar Species
