Leopard Seals are among the largest predators in Antarctic waters. They can be aggressive or playful. They have been known to attack and kill people. Nonetheless, photographer Paul Necklen sought them out. Sure enough, Necklen came face to face with a giant female. But she didn’t attack. Instead, she seemingly adopted Necklen. The teeth on this seal was amazingly sharp...They spent four days together  And the results were some stunning up-close photographs.
