These images show the unique bond a group of free divers formed with gigantic sperm whales. Swimming just inches away from the huge mammals, the divers are dwarfed in size, made to look like specks in comparison. The photos were taken by renowned underwater photographers Alexandre Roubaud and Alexandre Voyer, who are based in Paris but travel the world to capture such stunning imagery. Under the name Fisheye, the pair, who are longtime friends, have been working in the Indian Ocean and the Azores for the past five years. Their sperm whale encounter occurred this summer, and through their imagery, Alex and Alex hope to show the bonds humans can have with even the most intimidating of animals. Here: a diver with a sperm whales. (Photo by Alexandre Roubaud/Alexandre Voyer/Caters News)
