Spermatozoon structure and spermiogenesis inNassarius kraussianus(Gastropoda, Prosobranchia, Nassariinae) [PDF]

open access: yesInvertebrate Reproduction & Development, 1993
Summary The testis of Nassarius kraussianus (Nassariinae) produces two types of spermatozoa, a motile euspermatozoon and a non-motile paraspermatozoon. The euspermatozoon is filiform and about 95/μm long. The elongated head (40 μm long) is comprised of a slender nucleus (about 0.5 μm diameter) which is penetrated throughout by an intranuclear canal ...

ONTOGENY OF THE PSEUDOHERMAPHRODITIC REPRODUCTIVE SYSTEM IN NASSARIUS VIBEX (GASTROPODA: BUCCINIDAE: NASSARIINAE) [PDF]

open access: yesJournal Molluscan Studies, 2001
Pseudohermaphroditism or imposex is an abnormality of the gastropod reproductive system caused by the effects of an environmental pollutant, tributyltin, in which parts of the male reproductive tract develop in females. In this study, the post-larval development of the reproductive system in pseudohermaphroditic male and female Nassarius vibex was ...
