New research looking at the elaborate sounds produced by humpback whales is providing fresh insights into whale vocalization.
It's found that while humpback whales pass down calls through generations, their songs change frequently.
This suggests whale calls may have a different purpose to whale song.
Michelle Fournet from the Bioacoustics Research Program at Cornell University talks to Kathryn Ryan about the discoveries, and what we have yet to learn about the humpback whale's evocative acoustics.
