“Invertebrate Phyla at Race Rocks” is an introductory piece on some  of the invertebrate phyla that our divers encounter underwater . This was one of the first  streaming videos done by the Pearson College divers in April 2000. It was taken by Rowena and Shamsher on a Sony Digital camera, and edited by Hannah and Garry on a G4 Macintosh Computer using iMovie.
