From: Ultrastructure of oogenesis in imposex females of Babylonia areolata (Caenogastropoda: Buccinidae)
Pre-vitellogenic oocytes (PVO) and follicle cells (FC) of B. areolata. a Nucleus (N) of imposex female PVO with a large amphinucleolus (AN) and a small eunucleolus (EN). b The patches of nuage-like material (arrowheads) in the perinuclear ooplasm of imposex female PVO. c FC of imposex female. d FC of normal female. e FC of imposex female showing well developed Golgi body (G). f The round mitochondria with loosed cristae (asterisks) and tubular mitochondria with bipartition (arrowheads) in FC of normal female. db dense body, GV Golgi vesicle, L lipid droplets, M mitochondria, Nu nucleolus, RER rough endoplasmic reticulum.
