Kaikoura Krill, New Zealand, 1997

Just off the Kaikoura Peninsula, the ocean floor gives way to "an undersea canyon where currents mix and well up, producing a broth rich in nutrients. Drawn to the food are creatures great and small, from [these] tiny krill to the apex predator[s] ... the sperm whale and the giant squid."
