A cavaleiro - a horseman who targets the bull

Next come matadors who use a coloured cape, called a muleta, to direct the bulls around the ring.

Although the capes are usually bright red, all cattle are actually colour-blind. Red is often used to try to hide any trace of blood.

In Spain, the matador plays the leading role, killing the bull to the cheers of the crowd. But in Portugal the matadors make way for the forcardas.

A team of eight men called forcardas then show their bravery by standing in front of a bull. One of the team attracts the bull's attention and then it charges at the men.

As bulls can weigh up to half a tonne, it often knocks over one of more of the forcardas.

At the end of a fight in Portugal, the bull is dragged out of the ring and is usually taken to a butcher to be killed.
