After spinning a small water sample in my centrifuge at 4000 rpm for about 5 minutes I found a complex sample of specimens. In it were two nematodes, both fully extended that did not act like normal nematodes but looked dead. While all the ciliates, diatoms and bacteria were still very active the same did not apply to the worms. Perhaps the centrifuge killed or incapacitated them. I've since been informed this is one of the nematodes.
This ciliate was scampering around the slide, gobbling up diatoms as fast as it could find them.
