Right Column: Text descriptions of sounds:
  1. I use sound to tell predators not to attack me. If you get too close, I rattle my tail and hiss to say, “Stay Away!” I do not have ears. I use my jawbone to feel sound vibrations. That is how I hear what is around me.
  2. I live in the desert. I spend most of my days underground! To communicate with my friends, I thump my big feet on the ground. This is called “foot drumming.” Sometimes foot drumming will scare away predators.
  3. I travel with my friends. I use whistles to communicate with my pod. I also use high-pitched clicks that echo back to me. The echoes tell me what is around me and help me catch fish.
  4. I can be very loud. American Indians use me in different events. I also help keep the beat in your favorite music.
  5. I use my sense of hearing to locate prey above and below ground. I can hear a mouse squeaking 330 feet away. I use sound to communicate with my friends. I have 28 different barks, growls, whines, cackles, and howls.
