We know a lot about the language of large ocean mammals but it's just not as one to one with how we would translate it. The ocean is basically a noisy internet with their calls like alien packets that are mixed with a complex natural langue. Elephants have a similar thing. They make long sub-bass vocalizations that they can feel for miles with their feet.
As far as I know, prarie dog [0] is the closest we've come to a rosetta stone for another species. We can translate things like "brown fox north" and such.
