Swimming kinematics in (<i>A. anguilla</i>) with a PSAT dummy.

<p>A. Tail beat frequency (Hz) B. Tail beat amplitude (body lengths) and C. Body wave speed (body lengths) as a function of swimming speed (<i>U</i>, body lengths s⁻¹) swimming with and without a PSAT dummy. Swim trials without (control) and with a tag (trials 2, 3) were performed on the same individual (<i>N</i> = 9). Lines are regression lines (refer to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0020797#pone-0020797-t002" target="_blank">Table 2</a> for regression values). An <i>asterisk</i> denotes significant difference between control and tagged condition (Repeated measures ANOVA, p<0.05). Data are presented as mean±SD.
