Longfin Bannerfish

A master of innovation and a pioneer of high-tech underwater photography, Emory Kristof has helped National Geographic chart the waters of deep-ocean photography since beginning as an intern at the magazine in 1963. In his April 1998 story, "Testing the Waters of Rongelap," Kristof examined marine life, including these longfin bannerfish, in the nuclear weapons-contaminated waters surrounding the Marshall Islands.
