Comparative organization of follicle, accessory cells and spawning anlagen in dynamic semelparous clutch manipulators, the urochordate Oikopleuridae

Abstract

The organization of the female germline in the Oikopleuridae shares some features of meroistic oogenesis with the arthropod Drosophila, but the process of synchronous oogenesis in these semelparous organisms remains quite distinctive with respect to that previously characterized in the animal kingdom and certainly within the chordate phylum.
