Classification was made after histological examination of alcohol-formol-acetic acid-preserved gonad samples. Tissue embedded in paraplast wax after dehydration, sectioned at 5 µm and stained with ARTETA trichromic stain before examination. Data points from Table 20, figure 21 using Data Thief III software.
