The Esocidae are named after the pike genus Esox. One highly successful species is Esox lucius or northern pike.[2]
The Esociform fishes live in freshwater, in North America and northern Eurasia. The order is very similar to the Salmonidae.[3]
The family Esocidae has three extant genera (Esox, Novumbra, and Dallia) that comprise a holarctic distribution.
Umbridae is another family. So far, the genus Umbra is the only extant genus. The other genera have gone extinct.
