Occurred on January 17, 2017 / Falmouth Bay, Cornwall, United Kingdom
Info from Licensor: "I took this footage aboard my 16 foot commercial fishing vessel 'Stargazy Pie'. Dolphins were herding pilchards (sardines) and bringing them up to the surface to feed. It was indeed a spectacular sight to behold. I wasn't out looking for dolphins, rather simply fishing and seeing the diving gannets. Suddenly I realized that I was joined by a large pod of dolphins who came alongside and in front of my boat."
