Did you know that scientist have discovered that giraffes make sounds? They do it on an infrasonic level, which means that the sound is too low for human ears to detect. Infrasonic sounds can travel much longer distances than other types of sound. Giraffes usually use this ability when they separated or out of visual range of other giraffes. If we were to be able to hear this giraffe sound, it would sound like a gush of air!
