I remember that "cymascope" experiment that used a dolphin's sound as input. Turned out the water surface had an image (after lots of noise deblurring) of a human the dolphin just seen. This means the organ that decodes sound is a simple membrane with water. How dolphins encode images into sound is a separate question.

Since dolphins also 'see' with sonar, using the sonar response inflection of an object to refer to that object is sort of like an onomatopoeia.

I don't remember this but would extremely interested to see it. Any link?

It was one of John Stuart Reid presentations.
