From: Ultrastructure of oogenesis in imposex females of Babylonia areolata (Caenogastropoda: Buccinidae)
Early vitellogenic oocyte (EVO) of B. areolata. a Nucleus (N) of imposex female EVO with a nucleolus (Nu) containing electron-lucent space (ES). b EVO of imposex female showing nuage-like material (asterisk) surrounded by mitochondria that divide by bipartition (arrowhead). c Ooplasm of imposex female EVO. d Ooplasm of normal female EVO. e Golgi body (G) of imposex female. f The annulate lamellae (asterisk) in the ooplasm of imposex female EVO. CG cortical granule, GV Golgi vesicle, L lipid droplet, M mitochondria, V electron-lucent vesicle, Y yolk body. Scale bars = 0.5 μm (b, e, f) and 2 μm (a, c, d)
