FIGURE 3. Balanodytes taiwanus Utinomi, 1950, external morphology of female. (A) Lateral view of live female. (B) and (C) Posterior processes of opercular bars, opercular bars and orificial knob, showing variation in teeth number along the margin, lateral view. (D) and (E) Orificial knob, showing variation in teeth on surface, lateral view. (F) Opercular area observed under scanning electron microscope (SEM), upper lateral view. (G) Posterior process of opercular bars under SEM, showing teeth and setae, upper lateral view. (H) Orificial knob under SEM, showing teeth and sparse setae, upper view. (I) Comb collar under SEM, showing plumose projections. (J) Enlarged view of cuticular projections of comb collar. (K) Rows of massive multifid scales on opercular region. (L) Mantle teeth on surface of orificial knob. Abbreviations: cc—comb collar, ms—massive multifid scales, ob—opercular bar, obp—posterior process of opercular bar, ok—orificial knob. Scale bars in Μm.
