What is it?
The passing of information from one organism to another through the use of sound. Animals use different sounds for warnings, mating rituals, and for locating food sources. The sounds that animals make can be either very complex or very simple.
Dolphins use echolocation to figure out where objects are located. They send out sound waves, when the waves hit an object they bounce back to the dolphin.http://www.dolphins-world.com/dolphin-echolocation/
