California's coastal waters are home to a multitude of invertebrates (species lacking a bony skeleton). A small fraction of these, including bivalves such as clams and mussels, are actually targeted by California's recreational and commercial fisheries. In the following links, visitors can learn more about bivalve species identification, biology, habitat, geographic range, fishing methods, and more.
