Description Morphology of male reproductive tract and spermatogenesis of the potentially
commercial deep water crab Charybdis smithii were studied in specimens obtained
during the cruises of Fishery Oceanographic Research Vessel Sagar Sampada in
the Indian seas. Male reproductive tract is composed of testis, vasa deferentia,
ejaculatory duct and external penis. Vas deferens is classified into anterior vas
deferens (AVD), middle vas deferens (MVD) and posterior vas deferens (PVD). The
tubular testis comprises numerous acini or seminiferous lobules arranged around
central seminiferous duct. The spermatogenesis involves the progressive reduction
of cjftoplasm and only one developmental stage was found in one seminiferous
lobule at a time. The simple ellopsid spermatosphores are lodged in the AVD.
The epithelial cells in the proximal portion of AVD are cuboidal whereas distal
portion of AVD has columnar epithelial cells
