Imagine being able to see into another persons body, being able to see the flow of blood, the workings of the organs, and the flow of air into the lungs. Cetaceans can do this through echo-location. A dolphin can see a tumor inside the body of another dolphin. If an animal is drowning, this becomes instantly recognizable from being able to see the water filling the lungs. Even more amazing is that emotional states can be instantly detected. These are species incapable of deception, whose emotional states are open books to each other. Such biologically enforced honesty would have radically different social consequences from our own. Sight in humans is a space-oriented distance sense which gives us complex simultaneous information in the form of analog pictures with poor time discrimination. By contrast, our auditory sense has poor space perception but good time discrimination. This results in human languages being comprised of fairly simple sounds arranged in elaborate temporal sequences. The cetacean auditory system is primarily spatial, more like human eyesight, with great diversity of simultaneous information and poor time discrimination. For this reason, dolphin language consists of very complex sounds perceived as a unit. What humans may need hundreds of sounds strung together to communicate, the dolphin may do in one sound. To understand us, they would have to slow down their perception of sounds to an incredibly boring degree. It is for this reason that dolphins respond readily to music. Human music is more in tune with dolphin speech.
