Light sensitivity of GtACR1- and GtACR2-expressing fish. a, b Response of ACR1 fish to blue (a) and green (b) light of three different intensities (high, medium and low). For each panel, the top trace shows the movement of each fish in 1 s. This is measured by number of pixels that differ, relative to the cross-sectional area of the chorion. Each line represents one fish. The lower trace shows the mean value and 95% CIs. Controls refer to siblings lacking eYFP expression that were exposed to high intensity light. c, d Effect of blue (c) and green (d) light of different intensities on ACR2-expressing fish. e, f The effect of red light on ACR1- (e) and ACR2- (f) expressing fish. Line colour corresponds to the colour of light used for illumination. For all conditions, the period of illumination lasted from t = 15 s to t = 30 s
