Summary of turning kinematics (yaw) in male and female C. dalmanni. Values are the means per sex ±1 s.d. The p-values refer to the significance of sex effect in a mixed linear model (75 turns from 21 females and 70 turns from 20 males). All parameters were log transformed prior to the analysis. ω denotes angular velocity and the subscripts H, T and HT denote head, thorax and head relative to the thorax, respectively.
