Ocean Biodiversity - Discovering Marine Invertebrates

In this video, zoologist Dr. Karen Osborn explains how she discovers and names new species of marine invertebrates, such as acorn worms.


Meet Dr. Karen Osborn, 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 200-4000 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 signficance of ocean biodiversity for the systems that sustain life on Earth. This show aired March 26, 2015.
