The Atlantic thread herring (Opisthonema oglinum) is a saltwater fish of the family Clupeidae that grows up to 38 cm.
Description
The Atlantic thread herring is a silvery herring of the family Dorosomatidae (formerly Clupeidae) reaching about 38 cm. The laterally compressed body has a blue-green back, often a dark shoulder spot and, characteristically, a greatly elongated last dorsal-fin ray that trails backward like a thin thread - hence the name. With fine gill rakers the fish sifts plant and animal plankton from the water. The species forms large, fast schools that live pelagically in coastal water along the western Atlantic coast from the USA to Brazil. Through its great numbers it is an important prey fish for larger predators and seabirds and is much used as bait.
