I heard a crazy theory that this is how dolphins communicate. As they perceive using sound and are able to produce sound, perhaps they project the sound of the thing they want to talk about. It would be the same as a human being able to shine any image we like onto a wall to communicate. Can they recreate the echo of a fish with high enough fidelity that it's recognisable to another dolphin? |
