Today, animals for entertainment is a very booming industry. It was used much less in older times. Ancient Chinese peoples brought in wild crickets to play music for them. Ancient Romans brought lions and tigers into collusseums to hunt down slaves and victims. Also, other animals, like elephants.But today many more animals are used for entertainment. Aqua shows, animal tricks, pet shows and circuses all enlist animals for entertainment. Also, for hundreds of years, falcons and hawks have been trained to hunt in falconry. Dogs, horses, frogs, and even snails compete in races. Dolphins and seals often perform in aqua shows. Monkeys and elephants are also common performers in circuses, fairs, and shows. Today, the calls of crickets, dolphins, humpback whales, frogs and songbirds are used as music. Also are cock fights and bull fights. These fights are considered inhumane and are illegal in the United States.
