Commodus was also known for fighting exotic animals in the arena, often to the horror of the Roman people. According to Gibbon, Commodus once killed 100 lions in a single day. Later, he decapitated a running ostrich with a specially designed dart. and afterwards carried the bleeding head of the dead bird and his sword over to the section where the Senators sat and gesticulated as though they were next. On another occasion, Commodus killed three elephants on the floor of the arena by himself. Finally, Commodus killed a giraffe which was considered to be a strange and helpless beast. "Commodus killed a camelopardalis or giraffe...the most useless of the quadrupeds."
