Caption:
Under a magnification of 2500X, this digitally colorized scanning electron microscopic (SEM) image of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view, a microorganism is featured, the exterior of which is covered by numerous projections, imparting an appearance of a sea urchin. This microscopic pincushion was tethered to its surroundings by a biofilm, within which many bacteria and amoeboid protozoa could be seen enmeshed as well. See PHIL 11781 for a greater magnification of this organism’s exterior.
