Meet Dr. Karen Osborn, a zoologist at the National Museum of Natural History. Karen peers into the ocean depths using a remotely operated vehicle (ROV) to look for organisms. Take a visual journey with Karen 200-4,000 meters down to see the life she discovers in this mid-water habitat. Visit the surprising world below the ocean's surface, where polychaetes and other invertebrates abound. Find out how zoologists like Karen give names to the new species they find. Consider the significance of ocean biodiversity for the systems that sustain life on Earth.
