The motion of the sea urchin sperm flagellum was analyzed from high-speed
cinemicrographs. At all locations on the flagellum the transversal motion
and the curvature were found to vary sinusoidally in time. The curvatures
of the flagella increase strongly near the proximal junction. Two sperm are
described in transient from rest to normal motion. The full wave motion
developed in both sperm within 40 ms.
