Image of Ankistrodesmus Corda 1838

Description:

At a magnification of 1000X, 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 image, a needle-shaped structure appeared to be caught up in an amorphous gelatinous biofilm, which though unidentified, appeared to be the green algae, Ankistrodesmus. See PHIL 11664 for another view of this spear-shaped organism.
