From Expedition 5: As we investigate the submarine slopes of Galápagos volcanoes we see life that no one has photographed before. The creatures that live at these depths have adapted to a way of life in one of the world's most challenging environments. Learn more »

coralDeep-Sea Corals
From Expedition 7: When most people think of corals, they think big. Big, interconnected structures such as the Great Barrier Reef off Australia, which can be seen from the Space Shuttle.
