Ocean Biodiversity – Discovering Marine Invertebrates


  • Title: Ocean Biodiversity – Discovering Marine Invertebrates
  • Air Date: March 26, 2015
  • Series: Smithsonian Science How webcasts, which are designed to connect natural history science and research to upper-elementary and middle-school students.

This video features 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.

MS-LS2 Ecosystems: Interactions, Energy, and Dynamics

  • MS-LS2-1: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
  • MS-LS2-2: Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
  • MS-LS2-3: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
