A marine biologist from the Smithsonian Institution's National Museum of Natural History leads this astonishing expedition to the Galapagos islands, a world that is still relatively new & evolving. Descending to depths of 3,000 feet, the scientists find a window into the past & a frontier for exploration. The mission: collect rare & unusual species for study at the Smithsonian & elsewhere--all part of a real-life exploration that will discover what is believed to be more than a dozen new species of marine life.
