There has been many stories mentioning that the Colosseum had the ability to make wild animals appear. There has also been evidence of trap doors that could have allowed animals to pass for their battles.The display of exotic wild animals were an important part of the games. Originally the wild animals appeared as trained animal acts or to replicate hunting exploits. The types of animals used for these hunting shows were wild boar, bulls, bears deer, stags, dogs, wolves, goats and antelopes. These shows were called called venationes and the animal hunters were called venatores. The venatores were trained at a special training school called the Ludus Matutinus. The Ludus Matutinus, or 'morning school', was established by the Emperor Domitian who was himself a great hunter. A Lanista was in charge of the training at the Ludus Matutinus Training school and taking care of the animals. The Wild animals that were shown at the Colosseum were displayed as either clever circus acts where animals had been trained to do tricks or they were destined for death in the arena. Animals such as zebras and ostriches were trained to pull chariots. Ultimately their own death when the wild animals were fought by the gladiators, or used as targets in staged animal hunts, but they were also put in the Colosseum to attack and kill defenceless prisoners. The more exotic the animal, the better the fight and the better the quality of the 'games'
