Differential interference contrast image of Xenopus laevis sperm. These sperm have a helical head and swim in a helical trajectory. The 15 µm long head exhibits a textured mid‐piece at the rear into which the fl agellum is anchored. Attraction of these sperm to the egg‐derived protein allurin is studied by Sugiyama et al. in this issue.
