Amazing footage of a large pod made up of thousands of common dolphins that swim several miles to reach their target: a shoal of sardines. Besides the beauty of these dolphins and their astonishing jumps out of water, the sense of orientation they have is extraordinary, because despite the immensity of the ocean, they know exactly where to go thanks to its echolocation system which help them to know how far are their prey and how large are they. Can you imagine being able to witness such an exhibition? Certainly, the person who film it will never forget that moment.
