Just ahead of bellowing, males project an infrasonic signal at about ten Hz in the water, which vibrates the ground and close by objects. These low-frequency vibrations travel wonderful distances as a result of the two air and h2o to market the male's existence and are so powerful they lead to the drinking water's showing to "dance".[114]
