I cannot find it now, but there was some recent study that showed that dolphins can emit clicks which match echolocation returns, in essence communicating "images" to each other. Presumably this is what they're referring to.

I think that is an urban legend at this point. I also heard this claim from a colleague. When I did research I found nothing of the sort.
