Spermiogenesis particularities of a sperm storage species: <i>Helicolenus dactylopterus</i> (Teleostei: Scorpaenidae)

Females of this species have the capacity to store sperm within their ovaries, and male gametes have a considerable cytoplasmic mass surrounding their heads to survive the long period of intraovarian sperm storage. Our observations show that early spermatids are round-shaped cells and have a spherical nucleus with diffuse chromatin. The nuclear volume decreases as a result of progressive chromatin condensation du… Show more
