Figure 6


Fig. 6. Kinematic variables against fork length. (A) Head velocity; (B) tail velocity; (C) pectoral fin velocity, as the average of left and right fin velocities; (D) Reynolds number. (A) Head velocity had a slope not significantly different from zero. Tail velocity (B) increased with a slope of 3.32±1.03 and pectoral fin velocity (C) increased with a slope of 3.24±0.74. Since Re (D) was not measured directly but was calculated from other measured variables we did not include it in this analysis. We report the slope of its linear regression for general interest (slope=730±301). For further explanation of the regressions, see Statistics in Materials and methods. All graphs show mean value per individual, from 2 or 3 turning sequences.
