We examined the spermatozoa and their relationship with the ovarian lamellae in the catfish Trachelyopterus galeatus by classical light microscopy, high-resolution light microscopy, and transmission electron microscopy. Trachelyopterus galeatus is an internally inseminating species the spermatozoon of which presented an elongated cylindrical head (12.3 +/- 1.5 microm), elongated midpiece (5.0 +/- 0.7 microm), and flagellum (23.9 +/- 2.8 microm). Fertilized eggs or embryos were not found in its… CONTINUE READING
