Anchovies are a family of small schooling saltwater fish. In North America, anchovies include the northern anchovy (Engraulis mordax), occurring along the Pacific coast, from British Columbia to Mexico. They are small, silvery, and have a very large mouth. They most often occur in coastal waters relatively close to shore.
