I'm as or more cynical than the next guy - but it seems to me that being able to communicate with animals has high utility for humans. Partly from an emotional or companionship perspective as we've been doing with dogs for a long time, but maybe even on purely utilitarian grounds. If we want to know something about what's going on in the ocean, or high on a mountain or in the sky or whatever - what if we can just ask…
I am all for the Disney utopian fantasy of us living with animals. However if universal communication was to be made. Don't you think that animals are going to be pretty pissed to discover what we have done with their kingdom? "Hi Mr Dolphin, how's the sea today?" "Wet and a plastic bottle cap got lodged in my blowhole last night..."
So, the story involves an animal DNA archivist interacting with what's presented as the last living humpback whale, focusing on its isolation etc. It turns out the research lab's goal is to trick the whale by faking mating signals, aiming to get it to reveal information about whale history and culture. It's essentially data mining the animal.
