Blue whale underwater closeup photo.  This picture of a blue whale, the largest animal ever to inhabit earth, shows it swimming through the open ocean, a rare underwater view.  Since this blue whale was approximately 80-90' long and just a few feet from the camera, an extremely wide lens was used to photograph the entire enormous whale, Balaenoptera musculus

Blue whale close-up underwater portrait, taken breath-hold diving just a few feet away from the enormous blue whale with a fisheye lens.
