Description

The flatiron herring is a small herring-like fish of the family Clupeidae from the eastern Pacific. The species grows to about 18 cm and has a laterally compressed, silvery body with a blue-green back. It forms dense schools in coastal waters, often along the shore and in bays. As a filter feeder it sifts phytoplankton and small zooplankton from the water. As an extremely abundant prey fish it is an important link in the coastal food web for larger predatory fishes, seabirds and marine mammals, and is much used as bait. The species is harmless to humans.
