Correlation between Swimming Speed and Orientation Angle

Caption

(A,B) Track-averaged orientation angle (0 deg is vertical) versus track-averaged swimming speed (Vs; A) and track-averaged vertical swimming velocity (ws; B). Each point represents an individual 6-armed larva, using larvae from all turbulence regimes. (C-F) Probability distribution of track-averaged swimming speed in upright larvae (within ±25 deg of vertical; C) and tilted larvae (outside ±25 deg of vertical; D), and probability distribution of track-averaged vertical swimming velocity in upright larvae (E) and tilted larvae (F). Asterisks denote median speed or velocity for each distribution. Note that the x-axes for the tilted larvae (D and F) are reversed, so that they are mirror images of C and E, respectively.
