Resonating Devices in Nature for Communication and Information Reception

ABSTRACT Vibrations and resonance are pervasive means of communication and information reception in the animal kingdom. The tools, appendages, and organs used by an animal to amplify vibrations are known as resonating devices, which are the focus of this review. Animals from cicadas to lions employ resonating devices for functions…
