Esociformes

 Northern pike Esox lucius, copyright Jik Jik.

Belongs within: Protacanthopterygii.

The Esociformes are a Holarctic group of carnivorous freshwater fishes, characterised by the presence of preethmoids and paired proethmoids in the place of the mesethmoids, the absence of an adipose fin and of the orbitosphenoid and mesocoracoid, and the loss of teeth on the maxillaries (Bond 1996). They include the Esocidae, pikes, which are medium-sized to large fishes with a long, flattened snout.
