ray-finned fish

including the
tarpons,
tenpounders, and
ladyfish, as well as a number of extinct types. They have a long fossil record, easily distinguished from other fishes by the presence of an additional set of bones in the throat.
They are related to the order of
eels, although the adults superficially resemble very large or giant

Herring are various species of forage fish, belonging to the Order (biology), order Clupeiformes.
Herring often move in large Shoaling and schooling, schools around fishing banks and near the coast, found particularly in shallow, temperate wate ...

Classification
Although many fossil forms are known, the order is relatively small today, containing just two genera and nine species:Ectasis
Ectasia (), also called ectasis (), is dilation or distention of a tubular structure, either normal or pathophysiologic but usually the latter (except in atelectasis, where absence of ectasis is the problem).
