Salusan bulls are bovine animals native to Salusa Secundus. Their backs are covered with spines, their heads are black studded with multiple horns, and have faceted eyes. They have two separated brains.
A particularly fierce creature, Salusan bulls were kept in Caladan. Stablemaster Yresk tended the bulls for Duke Paulus Atreides for his occasional spectacles; however a Salusan bull was responsible for the death of Duke Paulus Atreides. After the Old Duke's death, the bull was slain.
Behind the Scenes Edit
Conceivably, this creature was one of the dangers that Imperial Sardaukar experienced when being raised on the harsh environment of Salusa Secundus during their training, and may have contributed to the high mortality rate experienced during their upbringing.
