This year’s humpback whale (Megaptera novaeangliae) season in Australia has almost come to an end. The beloved mammals are on their way to Antarctica for a summer of feeding. Next year from April onwards, millions of people will again witness their movements and acrobatic displays – either from the coast or by joining one of the hundreds of whale-watch boat operators.
But as much as we like to watch humpback whales, we still know very little about them. They are notoriously difficult to study in the field. While they are known for their surface activities, they spend most of their time underwater and outside the range of direct observations.
