Figure 3. Transmission electron microscopy (TEM) of potamid spermatozoa. A, B, Parathelphusula panningi. A, longitudinal sagittal view. B, cross section. C��F, Himalayapotamon emphysetum. C, longitudinal sagittal view; the arrowhead indicates the perforate operculum. D, 'tongue-and-groove' connection between the operculum and the acrosomal zones beneath.
