Body compressed from the sides, with jagged edge of abdomen. Scales moderate or large, rarely small. Upper jaw not protruding from lower jaw. The mouth is moderate.

Herring are found in all seas except the bitterly cold waters of the Arctic and Antarctic.
Most members of the herring family are marine. Some of them are anadromous and spawn in fresh water, and some species that are of freshwater origin stay out at sea. Herring usually move in vast schools. In the ocean, such schools can extend for many miles, making it possible to harvest fish in large quantities.
Herring can live up to 20-25 years, but it is rare to find fish of this age nowadays. The ongoing active industrial fishing significantly reduces the life span of herring. The maximum length is 46 cm and weighs about 2 kg.
