Salusan bull
From Wikipedia, the free encyclopedia
In the fictional Dune universe created by Frank Herbert, a Salusan bull is fierce and very aggressive creature with multiple horns, supposedly originating from Salusa Secundus. A Salusan bull killed Duke Paulus Atreides in a bullfight on Caladan; prior to the fight, the bull had been drugged to become more powerful and less docile. Its head is an heirloom that the Atreides bring to with them to Arrakis, though it is later taken as a trophy by the Baron Harkonnen.
