Elephants' Infrasonic Communication
Elephants use infrasonic communication, which involves sounds below 20 hertz that travel far distances even through dense forests. They can modify the structure of their vocalizations using their trunk, and different calls are used for different situations. Elephants can detect clouds forming from far away due to their excellent hearing at low frequencies.
