Re: wild dolphin seeks out human help

I was thinking about the encoding, and not the range. There is more than one way to embed a meaningful thing in a sound. Some of the known ways to do so are impossible to interpret or detect without a common reference, but thankfully those are always artificial and not something you'd see evolving naturally. It could still be something pretty elusive, though.
