Under a moderately-high magnification of 2500X, this digitally-colorized scanning electron micrograph (SEM) 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 pin cushion was teathered 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.Created: 2009

This digitally-colorized scanning electron micrograph (SEM) 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. Clearly visible in the center of this image, was a exquisitely-formed unidentified round vescicle-shaped microorganism, which may have been algal, or diatomic. Shaped like an ancient Grecian urn, the almost perfectly rounded smooth, flawless surface was made even more beautiful given its delicate structure.Created: 2009
