A cross section through the base of the sperm spike demonstrates the slightly compressed cross striation (due to the angle of the section) of the anastomosing radial fibrils. Bar = /im. FIGURE 11. At the tip of the spike cross sections reveal microtubular structures (arrow) in cross section. Similar structures have not been observed in longitudinal sections. Bar = /*m. FIGURE 12. The radial fibrils of the cap-like region of the base show the same cross-striated ap- pearance and presence of 6 nm filament

The radial fibrils of the cap-like region of the base show the same cross-striated ap- pearance and presence of 6 nm filaments as are present in the sperm spike. Bar = ^m. FIGURE 13. Interconnecting fibrils between the radial fibrils of the base and the centriolar matrix are also observed in cross section of the sperm base and contain cross striations and filaments as observed in the spike and the radial fibrils. Bar = nm. FIGURE 14. Centrioles are located in the main body of the sperm (arrows) and as shown in this section are housed acentrically at the base of the spike. Bar = aldehyde. These whorls appear to be equivalent to the perinuclear vesicular region described in the sperm of Palaemonetes paludosus (Brown, 1967; Koehler, 1979). Koehler (1979) identified a PAS positive reaction in this region of the sperm and.
