We examined the morphological features of spermatozoa from Conger myriaster by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Spermatozoa consisted of three regions, a head, neck and flagellum. Total length was approximately 40μm, with the head 3μm, neck 0.5μm and flagellum about 37μm. The head was crescent-shaped, with a mitochondrion on the concave surface. The neck, with an attached rootlet, consisted of two constrictions close to the base of the flagellum. Two bundles extending from the proximal centrioles existed on both the convex and concave surfaces of the sperm head. The flagellum showed a 9+0 axonemal pattern. Some flagella showed a coiled form, the developmental mechanism of which was unclear. These features were compared with those of other Anguilliformes.
