Spermatozoon ultrastructure and its systematic implications in fishes
We have studied approximately 280 species spread over more than 100 families. New data on 80 species are reported. The spermatozoon of Chondrichthyes is characterized by two synapomorphies in the… Expand

Peculiarities in the organization of testis of Ophidian sp. (Pisces Teleostei). Evidence for two types of spermatogenesis in teleost fish
The walls of lobules in the testis of Ophidion sp. are composed of Scrtoli cells and young germinal cells (spermatogonia and spermatocytes). Spermatocytes are linked by cytoplasmic bridges. The… Expand

Etude ultrastructurale de la spermiogenèse et du spermatozoïde d'un Plathelminthe: Gonapodasmius (Trematoda:Didymozoidae)
The technique of serial sections has been employed to study spermiogenesis and spermatozoon of Gonapodasmius. The zone of differentiation (ZD) shows no centriole-like body and no striated root.… Expand

Demonstration of the orientation of the Cestodes spermatozoon illustrated by the ultrastructural study of spermiogenesis and the spermatozoon of a Cyclophyllidea: Thysaniezia ovilla, Rivolta, 1874.
Spermiogenesis in Thysaniezia ovilla begins with the appearance of a differentiation zone equipped with peripheral microtubules, surrounded by arched membranes and containing two parallel centrioles… Expand

Comparative ultrastructural study of spermiogenesis in monogeneans (flatworms). 2. Heterocotyle (Monopisthocotylea, Monocotylidae)
The mature spermatozoon of Heterocotyle is threadlike and uniflagellate; however, the spermiogenesis exhibits two axonemes. The early zone of differentiation of the spermatid contains two centrioles… Expand
