Ctenoluciidae

They have elongated, pike-like bodies, and several sharp and conical teeth. They are relatively large, up to  in length, predatory fish. Some of these fish, such as Ctenolucius hujeta, enter the aquarium fish hobby, often being labeled a "freshwater barracuda" or "freshwater needlefish", descriptions of fish that are both unrelated to members of this family.

The two genera in this group are:
Boulengerella (five species)
Ctenolucius (two species)
