Male and female reproductive morphology in the inseminating genus Astroblepus (Ostariophysi: Siluriformes: Astroblepidae)
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
The structure of the reproductive organs of males and females of four species of Astroblepus were studied by light microscopy and TEM. In females, the gonadal and urinary orifices are separated. The urinary pore opens at ...

Spermiogenesis and introsperm ultrastructure of Scoloplax distolothrix (Ostariophysi : Siluriformes : Scoloplacidae)
(Wiley-Blackwell, 2006-10-01)
Spermiogenesis in scoloplacids is characterized by initial lateral development of the flagellum, nuclear rotation, medial nuclear fossa formation, complex centriolar migration, and cytoplasmic channel formation. The ...

Morphology and histology of male and female reproductive systems in the inseminating species Scoloplax distolothrix (Ostariophysi : Siluriformes : Scoloplacidae)
(Wiley-Blackwell, 2008-09-01)
The morphology and histology of male and female reproductive systems were examined in Scoloplax distolothrix. Internal insemination was documented in this species by the presence of sperm within the ovaries. Mature males ...
