Ricci Schwarzler, Underwater World of Gannets (Doco/Photojournalism (2018))

Off the Shetland Islands in the North Sea, Gannets hit the water at 40mph. They have air bags in their heads and bodies to take the impact. Their bodies streamline like the Concorde did at supersonic speed. From the boat we throw dead mackerel (one at a time) into the water. The birds circle around, swarming. They start to screech just as they start to dive. The shutter goes crazy and I hope I got a good shot. It all happens so fast. They eventually slow down under the water, once they have bled off their speed and they start to fly underwater to the fish. They can be over ten metres down. Once they have their fish and if others haven't fought them for it, they hit the surface, only to be attacked by the northern hemisphere's giant seagulls. Hopefully they can hang onto the fish which is now part way down their gullets, and they make the dash back to the cliffs to their young.
