Sardines are an important part of the food chain. Jupiterimages/Photos.com/Getty Images. Sardines live in large schools that may contain thousands of fish. They typically feed on plankton and are close to the bottom of the food chain; many different kinds of predators eat sardines, including humans.
Sardines, or pilchards, are common names used to refer to various small, oily fish within the herring family of Clupeidae. The term sardine was first used in English during the early 15th century and may come from the Mediterranean island of Sardinia, around which sardines were once abundant.resh sardines are often grilled, pickled or smoked, or preserved in cans. Sardines are rich in vitamins and minerals. A small serving of sardines once a day can provide 13 percent of vitamin B2; roughly one-quarter of niacin; and about 150 percent of the recommended daily value of vitamin B12.
