Figure 3

Three representative sperm motility patterns of naked mole-rat spermatozoa recorded at 50 frames/second. Red line = VCL, blue line = VSL and green line = VAP. The kinematic data for each track is shown on its immediate right (cut off values based on VCL (μm/s) = Fast > 45 > Medium > 35 Slow). VCL = curvilinear velocity, VSL = straight-line velocity, VAP = average path velocity, LIN = linearity, STR = straightness, WOB = wobble, ALH = amplitude of lateral head displacement, BCF = beat cross frequency.
