_____ play games by producing ultrasound.
Rats
Ultrasound refers to sound waves with a frequency higher than 20,000 Hz, which is beyond the upper limit of human hearing. Several animals produce and detect ultrasound for communication, navigation and social interaction.
Rats produce high-frequency ultrasonic calls during play, mating and social bonding, which researchers describe as 'rat laughter'. Whales and elephants use very low-frequency infrasound, while moths mainly detect bat ultrasound rather than producing it for play.
Hence, Rats.
