Insects Communicate Through Sound


Some animals and insects communicate at frequencies that humans can’t hear. Elephants and whales, for example, can find their families and mates using different frequencies. Crickets create vibrations that identify their species to other crickets, which helps to increase the cricket population. Sounds that people don’t pay attention to or sounds that people can’t even hear are all around us. Listen to this story to hear more about these sounds and how they have evolved to help animals survive.
