Figure 2. Boxplots of the variation in mean size (in mm²) of specimens.

Size is estimated by the mean area in pixels covered by the specimen in each image taken by the BIODISCOVER during its passage through the ethanol-filled cuvette. Size in pixels is translated into mm² based on the estimate that 10 mm width equals 496 pixels resulting in an approximate pixel size of 4.06 ×10⁻⁴ mm².
