IMHO translation of anything interesting requires the cultural background for context. To do it with a new language requires the translator to "go native". The mega fauna gets media attention, but they would have more chance of success with one of the many dolphin pods that live up close and personal with humans. For example Shark Bay: https://en.wikipedia.org/wiki/Monkey_Mia In the 1990s we had field linguists interested, but the tech sucked. It's good to try again, but a lit search might help.
