Brownian Motion inside Diatom 1000x

The Diatom and surrounding Cyanobacteria were from Heron's Head Park Salt Marsh, San Francisco Bay. Magnification was 1,000x under Hoffman Modulation Contrast optics. Camera was a Nikon Coolpix 885 at 3x zoom. The particles inside the Diatom exhibit Brownian Motion [see "Brownian Motion" Wikipedia for details]. It is not clear what the particles may have been. I doubt they were bacteria. It is more likely that each particle was either a mycelle or a vesicle [see Wikipedia for both terms]. Life is, indeed, wondrous to behold. What "miracle" could compare with this very common biological and physical event? [see Wikipedia for "miracle".]
