Fig. 3From: Morphological differences in tardigrade spermatozoa induce variation in gamete motilitySpermatozoa trajectories Obtained trajectories, normalized waveforms and curvatures of the heads and tails in the respective species. “Straight” and “Turn” indicate a spermatozoon swimming in a straight line and turning, respectively. Coloured lines of obtained trajectories correlate to waveforms in right panelsBack to article page
