Rotifer digestive system
This rotifer (Brachionus sp., I think) was vital stained using 20 ppm Neutral Red perfused from the margin of the coverslip into a well slide. Neutral Red stains lysosomes in living organisms, thus staining the stomach and here its contents. The photo on the left shows the intestinal contents before excretion and at the right after excretion. Specmen from a Northern Indiana lake.
