The genus containing trout and salmon species native to the North
Pacific Ocean and the rivers emptying into it. The name 'Oncorhyncus'
means 'hooked nose', a reference to the shape the fish's upper jaw metamorphoses
into when it attains sexual maturity, as it returns to the site of its
birth to spawn (and die).
