Process of cytoplasmic elimination during spermiogenesis in two cyprinodontidae (Teleostean fishes)
The mechanism of excess cytoplasm elimination during spermiogenesis was studied in two Cyprinodontidae species Aphysemion riggenbachi and Aphyosemion splendopleure. The cytoplasm is progressively filled with numerous vesicles resulting mainly from the phenomenon of pinocytosis. These vesicles coalesce and give birth to concentric cisternae in the aged spermatid. The residual body is formed by this membranous system.
