In this photo hundreds of nematodes, Steinernema (formerly Neoaplectana) carpocapsae (Weiser), were released in the center of the petri dish (bottom center). The dish was filled half way with
agar and then a thin film of India ink (carbon particles) was poured over the agar. The nematodes "plow" the carbon particles causing
their paths to show up under illumination. The paths appear to be rather random with a forward component, much
as the paths of any moving animal is in the absence of any landmarks.
