Ultrastructure of the spermatozoon of Bothriocephalus claviceps (Cestoda, Pseudophyllidea): a parasite of Anguilla anguilla (Fish, Teleostei).
International audience The mature Bothriocephalus claviceps spermatozoon is filiform and tapered at both extremities. It contains two axonemes of unequal lengths of the 9+"1" pattern of the trepaxonemata. The anterior extremity exhibits an apical cone of an electron-dense material about 6....
