FIGURE 4. Longitudinal distribution of paragnaths in the furrow and ridge regions. A, Neanthes cf. acuminata (ECOSUR P2936), showing the longitudinal alignment of paragnaths. B, same, diagram of the distribution of paragnaths in a pharynx fully everted. C, Nereis pelagica (ECOSUR P2840), showing the irregular distribution of paragnaths. D, same, diagram showing the paragnaths longitudinally aligned, paragnaths of the same color belong to the same longitudinal row. E, same, diagram showing longitudinal rows obtained when connecting the dots (paragnaths) of the same row
