How many bulls die at one bullfight?

In a standard bullfight there are three matadors and each kills 2 bulls. That is a total of six bulls. At times, however, there will be only two matadors and each will kill 3 bulls. This is called mano a mano. Even more rare, a particularly popular matador may fight 6 bulls alone. In any case, six bulls are the standard. Some smaller venues with less resources may have fewer animals and fighters.
