List out the animals that communicate using infrasonic and ultrasonic sound.

Hint: Sound waves as we know require medium to travel. Sound waves propagate through the air medium. And interestingly, as human beings are able to use sound waves to hear as they speak, the waves travel and the brain with the help of sensory nerve cells transforms the information and processes it in order to understand. Animals also communicate by using sound waves.

Complete answer:
Animals also communicate by sound waves. Sound waves like-infrasonic and ultrasonic waves help animals to communicate to other animals. Animals like- whales, elephants, hippopotamus, giraffes, peacocks communicate over infrasound.
Infrasound works in low frequency like as in human audibility ranges generally from twenty hertz. So, infrasonic refers to sound below the human range. Animals have lower intensity than human beings. Their sensory organ captures waves below the twenty hertz. Animals which live in water like- dolphins, whales require high intensity waves as in water sound waves find difficult to travel in water.
Insects and bats, dogs beetles, toads, these animals communicate through ultrasonic sound waves. Ultrasonic sounds emit frequencies up-to twenty thousand hertz. They have much higher frequencies to communicate and be able to hear.

Note:
So, we discussed the difference between waves and which animals communicate through infrasonic and ultrasonic waves. Animals like bats and dolphins use their sound as echoes as they are blind animals and cannot locate objects so, they use the sound waves to determine the objects and catch prey or for locomotion. Human beings can hear ultrasonic, though the range is much higher than the human range. But we can perceive it.
