Ultrastructural study of the mucosa of the male gonoduct ofMurex brandaris (Hexaplex brandaris)(Gastropoda, Prosobranchia)

Summary The male gonoduct of Murex brandaris (Hexaplex brandarte) is covered by a columnar ciliated epithelium in which some goblet cells are located at the first level of the gonoduct. The structure of these cells suggests a transport and secretory epithelium. Some differences in ciliary organization and in cellular junctions are shown. The presence of some abnormal cilia is also detected.
