Image of Hexamitidae

Description:

This 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 number of unidentified oblong elliptical-shaped diatoms were featured, along side amorphically-shaped masses of organically-composed biofilm.
