Northern gannets are the largest seabirds in the North Atlantic. They fish by diving into the sea, they can do it from a height of 30 meters with a speed of 80 km/hour, and pursuing their preys underwater. The island of Noss, in Shetland Islands, is one of the most important nesting point, with over 7000 breeding pairs. I took this picture in front of the high cliffs, from a small boat using an underwater housing, and surrounded by thousands of gannets flying, diving, shouting around me …an amazing nature show!!
