Nematodes are funny. I was curious, so I bought a simple inspection microscope and bought some agar plates with E.Coli on them. You can easily sample nematodes by cutting up rotting fruit and putting it on the edge of the plates. the nematodes will cruise out of the fruit and cruise around the E.Coli eating it, leaving tracks. Then you can make a worm pick, isolate and clean nematodes, and transfer them to other plates or slides for closer inspection.<p>Of all the model organisms, C. Elegans is far and away the most amazing.
