Abstract

The structure of the sperm of Liza dumerili was studied by light microscopy and scanning and transmission electron microscopy. The sperm have a kidney-shaped nucleus. The ""hilus"" faces posteriorly and the proximal centriole is situated within the nuclear pit. Nuclear rotation takes place during spermiogenesis and the sperm are therefore related to those of other teleosts showing Type I spermiogenesis. No acrosome is evident. The midpiece is small but distinct and contains four spherical mitochondria. The flagellum enters the midpiece eccentrically and the axoneme runs obliquely towards the distal centriole to which it is connected. The flagellum conforms to the 9 + 2 flagellar pattern.
