The shortjaw kokopu (Galaxias postvectis) is a galaxiid fish, endemic to New Zealand. They are large, scaleless fish which inhabit stable pools in cascading, bouldery streams with forest cover.[2] Shortjaw kokopu are amphidromous, with the fry going to sea after hatching, and returning as juveniles to fresh water where they grow to adulthood.[2] 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).[2]
