A hunter, huntress, or huntsman was someone who followed and captured prey, i.e. other lifeforms, to kill or to secure them. Many cultures practiced hunting for various purposes such as ceremonial, for sport, or simply as a means to obtain food. Species known for their hunters were the Klingons, the Eska, the Hirogen, and the "Hunters". (ENT: "Rogue Planet"; DS9: "Captive Pursuit", "In Purgatory's Shadow"; VOY: "Hunters")
