Figure 2. Some chaetal shafts of nereidid genera and species detailed in Table 2. The shafts are grouped following the criteria proposed in this work and are ordered from the lowest (left) to the highest (right) difference between the inner and outer collar in homogomph shafts and between the outer collar and the boss in sesquigomph and heterogomph shafts. Dotted yellow lines show the angle formed by the collar rim and the place where the width measures of the inner and outer collar were made. Codes for species are found in Table 2. Scale bars: 10 µm.
