Extreme diversity in the songs of Spitsbergen's bowhead whales
Almost all mammals communicate using sound, but few species produce complex songs. Two baleen whales sing complex songs that change annually, though only the humpback whale ( Megaptera novaeangliae ) has received much research attention. This study focuses on the other baleen whale singer, the bowhe...
