Paulinella

Paulinella is a genus of amoeboidprotists with at least twelve species of freshwater and marine euglyphids. Like many other euglyphids, it is covered by rows of siliceousscales, and use filose pseudopods to crawl over the substrate of the benthic zone. Species within the group can be distinguished by features like the overall shell dimensions, the number of vertical scale rows (3–5), the number of scales per row (7–14) and the number of oral scales.
