The Tuned Cricket.
Communication by means of sound is not always easy. Sound suffers much attenuation and degradation close to ground. Crickets have adapted to this by exploiting sharply tuned mechanical systems. A coevolution ensures that the calling song of males and the directional hearing of females are tuned to the same frequency.
