Image of Hexamitidae

Description:

At a magnification of 2000X, this scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream, which is mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular image, an expanding amorphous organic biofilm was featured within which numbers of amoeboid protozoa seemed to be embedded. For a colorized version of this image see PHIL 11714.
