Each year since 2015, I have given this lecture on Metazoan Diversity to UC Berkeley's EPS/IB Oceans C82 course which includes a brief overview of the diversity of invertebrates in our oceans. This video is designed for educational purposes only and features the following videos: Sponge Video: https://www.youtube.com/watch?v=m8a0oNsDEx8 Swimming Anemone Video: https://www.youtube.com/watch?v=Dm98n3908QM&t=10s Jelly Birth Video: https://www.youtube.com/watch?v=4Zi1DCfcVqU&t=552s Disco Clam Video: https://www.youtube.com/watch?v=EAB-8spi7Xg Dendronotis Carnivorous Nudibranch Video: https://vimeo.com/231458910 Mimic Octopus Video: https://www.youtube.com/watch?v=os6HD-sCRn8 Bobbit Worm Video: https://vimeo.com/28280553 Mantis Shrimp Video: https://www.youtube.com/watch?v=DtNAqK_V-lg Mantis Shrimp v.

Calcium is vital for many biochemical processes, from intracellular communication to bone and shell formation. Join marine biologist Jessica Kendall-Bar to learn how minute plankton shells play a critical role in pumping carbon from the atmosphere to ocean depths. Jessica Kendall-Bar studied Marine Science and Integrative Biology at the University of California, Berkeley. A scientist and artist, she is passionate about communicating scientific discoveries through illustration and animation. While at Berkeley, Jessica participated in a series of oceanographic expeditions with chief scientist Dr. Jim Bishop, studying the patterns of biologically driven carbon sequestration in the ocean.
