FIGURE 1. Morphometric characteristics of Difflugia australis from Shidou Reservoir, Xiamen, China. (A) Shell outline (lateral and apertural views) showing covering of irregularly shaped, flat particles and position of measured morphometric axes in this study. 1–total shell length, 2–shell width, 3–aperture diameter, 4–collar height, 5–body length, 6–spine length. (B) Frequency plots of shell dimensions. Histograms showing the size frequency of aperture diameter (left column), shell width (middle column) and total shell length (right column). (C) Frequency plots of mineral dimensions. Histograms showing the size frequency of apertural mineral perimeter (left column), body mineral perimeter (middle column) and spine mineral perimeter (right column).
