Analysis showed E. reimeri ranges in size from 38 to 89 µm in length and 16 to 26.5 µm in breadth; these measurement extended the reported size metrics (L 30-75 µm, B 17-22 µm; Spaulding et al. 2010). Shorter valves had less attenuated ends and less tumid ventral inflations. There is a positive relationship between valve length and breadth (Fig. 2), and a weak negative relationship between striae density and cell size.
