Fig. 9. Magnitude of kinematic variables for body and fins during manoeuvres. Fish body sides, and their respective fins, are defined as inside (the side closest to the direction of the turn, yellow) and outside (the side farthest from the direction of the turn, blue). Fin area was measured in cm², angles were measured in radians, and velocities were measured in cm s^–1. Asterisks above bars denote significantly different values within fins (P<0.05). Asterisks below bars denote significantly different values between fins (P<0.05). Solid colours represent maximum values and diagonal lines represent minimum values. All between fin comparisons were not significant, with the exception of fin angle with the flow sagittal plane (abduction and adduction) and with the fish sagittal plane (adduction only, P<0.05). Fin area, and fin angle with the sagittal plane (fish and flow axes) had significant interaction between fish and fin (P<0.03). The differences in these variables between individuals suggest fine-tuned adjustments of fin surface area and mediolateral motion during manoeuvres, which possibly affect roll stabilization.
