Which animal is known to communicate using infrasound?
Rhinoceros
Infrasound is sound with a frequency below 20 Hz, which is too low for humans to hear. Such low-frequency waves travel long distances, so some large animals use them to communicate over great distances.
The rhinoceros is known to communicate using infrasound, producing low rumbling calls that carry over the wide areas they inhabit. Elephants and whales are other well-known infrasound users.
Dolphins and bats instead use ultrasound, which is high-frequency sound above 20,000 Hz, for echolocation to find prey and navigate, the opposite end of the frequency range.
Rats also communicate largely in the ultrasonic range, emitting high-frequency calls, not infrasound.
Hence, the animal known to communicate using infrasound is the rhinoceros.
