Whale vocalizations are a bit of a mystery. We know that only the males of some baleen whales sing, but we’re not sure what those compositions—specifically structured phrases and melodies that repeat and evolve within their whale communities over many seasons—are communicating. Could it be a tool for finding a mate or deterring the competition? Could it be an important part of how they migrate? Or could they be communicating the story of their pod in a way we don’t yet understand?
