Matadors' bulls, also known as toros, are bulls that are used in bullfighting. Bullfighting is a traditional Spanish sport in which a matador attempts to fight and kill a bull in a ring. The bulls used in this sport are specially bred for their strength and agility. They are usually between four and six years old and weigh up to 1, 000 pounds. The bulls are trained to respond to the matador's movements and commands. The matador must use skill and courage to outwit the bull and ultimately kill it.
