These fish are mostly silver in color with brassy sides and a dark blue-green back. They can be identified by a large spot on the shoulder with numerous little spots on the sides and their disproportionately large head. They grow to 16" (40 cm) in length, feed on plankton, and are preyed upon by whales, porpoises, tuna, and other larger fish. These fish are extremely oily and are harvested for their oil. They are made into fertilizer and fish meal. They are a poor food source but make excellent bait. They commonly swim in large schools near the surface and are found in Narragansett Bay during spring, summer and fall.
