Gladiator games weren't the only events held at Roman coliseums. Venationes, wild animal hunts, were also staged. Exotic animals, such as elephants, lions and crocs, were hunted by one another and hunted by man. To make the hunt look real, the Romans built deserts, hills and waterways inside the arena. To ensure a good fight, the animals were starved for days before the show. Animals and hunters were maimed and killed while the audience watched. Trajan staged the largest Venationes. His spectacles included more than 10,000 gladiators and more than 11,000 animals.
