What is the Fibonacci sequence? And why did Fibonacci himself use 'a field of incestuous rabbits' to demonstrate it? Made in partnership with #BBCIdeas | The Royal Society

Drone footage of hunting whales shows an example of the Fibonacci spiral occurring in nature, where the two whales can be seen working together to create a bubble net surrounding fish. Bubble-net feeding is usually observed in groups of four or five humpback whales, where the whales dive down several hundred feet, releasing a stream of air bubbles in a spiral pattern “at a precise moment and in an exact sequence," according to research. https://abcnews.visitlink.me/QM-cQK | ABC News
