The shortjaw kōkopu is a galaxiid ray-finned fish, endemic to New Zealand. They are large, scaleless fish that inhabit stable pools in cascading, boulder-strewn streams with forest cover. Shortjaw kōkopu are amphidromous, with the fry going to sea after hatching, and returning as juveniles to fresh water where they grow to adulthood. They may grow to a maximum of 350 mm (14 in) in total length, but more commonly reach 150–200 mm (5.9–7.9 in).
