A Dinoflagellate dances over a Cyanobacteria. Videomicrograph with a Nikon Coolpix 885 at 3x zoom, through Olympus microscope 1,000x oil immersion, Hoffman Modulation Contrast optics. Many small microorganisms cluster around Cyanobacterial filaments. Some, like ciliates come for the oxygen. I am not sure what attracted this Dinoflagellate.
are you sure that is a dinoflagellate?

Yes, this Dinoflagellate is found throughout the San Francisco Bay salt marshes and salterns at salinity above around 30-PPT. At this magnification [1,000x) in older preparations the two flagella, transverse and longitudinal, as well as the sulcus are readily seen as they move much more slowly. I have not identified the genus or species.
