Figure 1—supplement 1. Larvae tend to sink between bouts.

(A) Schematic of hydrostatic forces acting on larvae absent lift during bouts (top) and between bouts (bottom). (B) Trajectory as a function of swim speed, plotted as means of equally-sized bins for four clutches (gray lines) and their mean (black). Swim bouts (light gray band, speeds faster than 5 mm·s⁻¹) tended slightly upwards, while larvae sank at slow speeds, particularly slower than 0.1 mm·s⁻¹ (dark gray band). (C) Polar probability distributions of trajectories during swim bouts (light gray, top) and at speeds slower than 0.1 mm·s⁻¹ (dark gray, bottom). (D) Vertical displacement during the interval between two bouts (when speed decreased below 5mm·s⁻¹) as a function of interval duration, for individual bouts and mean of equally-sized bins.
