FIGURE 3. Polydora ecuadoriana adult morphology and distribution of fertile (gametogenic) chaetigers, São Paulo and Paraná. A, relationships between number of eyes and total number of chaetigers in worm, and distribution of number of eyes in population. B, relationships between pigmentation of palps and total number of chaetigers in worm; abs —absence of pigmentation on palp; line —black line along longitudinal ciliated groove on palp; 2–7 —number of black bars on palp. C, relationships between length of caruncle and total number of chaetigers in worm. D, relationships between position of the first and last fertile chaetigers and total number of chaetigers in males. E, same in females.
