Fig. 5. Angle of pectoral fin movement during the braking maneuver for protraction (degrees) vs time (s) for S. radians (blue squares) and S. quoyi (green circles). (A) Plots of pectoral fin protraction in two representative individuals of Sparisoma and Scarus. (B) Pectoral fin protraction angle (mean ± S.E.M.) for Sparisoma and Scarus during braking. (C) Difference in stroke plane angle (degrees) between cruising and braking maneuvers for Sparisoma radians and Scarus quoyi. Contact with food item occurs at t₀, indicated by broken vertical lines.
