Fig. 6 in Spermatic characteristics and sperm evolution on the subfamily Stevardiinae (Ostariophysi: Characiformes: Characidae)
Fig. 6. Spermatozoa of Bryconamericus exodon. A-E: Longitudinal sections of spermatozoa. Note the lateral position of the nucleus (n) in relation to the flagellar axis and to proximal (p) and distal (d) centrioles, the position of the double nuclear fossa (double arrow), the mitochondria and the endomembrane system of the midpiece and the cytoplasmic canal (*) containing the initial segment of the flagellum (f). A-Inset: Detail of the position, shape and depth of the nuclear fossa, and the position of the centrioles to one another and to the nuclear fossa. F-L: Cross sections from the middle to the base of the nucleus and at different levels of the strongly asymmetric midpiece exposing the lateral position of the cytoplasmic canal (*) and of the flagellum (f), the distribution of the few elongate mitochondria (m) accumulated in larger portion of the midpiece and the lacy aspect of endomembrane system (v). L-Inset: Cross section of the flagellum with the classic axoneme (a).
