Humpback whales are renowned for their charismatic, awe-inspiring behaviours above and below the ocean’s surface. Humpbacks frequently launch themselves into the air and land with a splash, known as breaching. They also slap the surface of the water with their long, jagged pectoral fins, the largest relative to body size of any whale. Their equally huge flukes are uniquely marked with mottled patterns like fingerprints, which scientists use to identify individuals using photo-identification catalogues. Humpbacks can also be tracked acoustically, as they sing the most complex songs of any marine mammal and can be heard from hundreds of kilometers away. These songs are often repeated for hours by males to attract females, and can change over time as whales learn new dialogues from each other. Their incredible social behaviours don’t stop there: humpback pods will feed together by encircling a school of small fish with bubbles, condensing them in a so-called ‘bubble net’ for easy capture with a single lunge.
