Microanatomy of P. verrucosa. A) 3D-reconstruction of the central nervous system, frontal view (ZSM Mol 20071832). B) Histological semi-thin section of the cerebral ganglia showing unpigmented eyes and rhinophoral ganglia. C) 3D-reconstruction of the male reproductive system in a partially retracted specimen, right lateral view (ZSM Mol 20071833). D) Histological semi-thin section showing prostatic vas deferens and sperm-filled ampulla (arrowhead = dark blue stained epidermal gland). E) 3D-reconstruction of the female reproductive system in a completely retracted specimen, right lateral view (ZSM Mol 20100548). F) Histological semi-thin section showing nidamental glands and gonad with oocyte.
