The photographs, taken off the coast of Isla Mujeres, near Cancun, Mexico, show how these water creatures work cooperatively to cut off a portion of a school of sardines swimming close to the seafloor, and drive them to the surface. American photographer Doug Perrine, 60, managed to capture the moment the sailfish manage to herd the bait into a tightly packed ball, ready to pick off for dinner one-by-one. ‘The sailfish took-turns swimming through the bait ball slashing with their bills to kill the fish, which are quickly gobbled up,’ Doug said. ‘Sometimes they light up or change to a bright colour pattern.
