Locally restricted swimming after loss of illumination. a Representative path trajectories for a larva during full field illumination (left panel) and during the first 10 min after loss of illumination (right panel). Arrowheads denote starting position and numbers indicate time (min). Color scale indicates fractal dimension in 30 s windows. Main scale bar 10 mm, chamber is 200 × 200 mm. Arrowhead length equivalent to larva length. b–e Displacement, meander, fractal dimension, and trajectory bias for larvae measured during 10 min of full field illumination (yellow), followed by 10 min darkness (black). N = 32. * P < 0.05, paired t-test compared to corresponding baseline time-point. See Methods for description of measurements
