Circus animals are trained creatures that perform in shows for entertainment. Common types include elephants, lions, tigers, and horses. These animals often learn tricks and routines through positive reinforcement and repetition, showcasing their skills in front of audiences. The use of animals in circuses has sparked debates about animal welfare and ethical treatment. Many organizations advocate for the protection of circus animals, arguing that their training and living conditions can be harmful. As a result, some circuses have shifted to using only human performers or have ceased operations altogether.
