Fig. 5

Time needed for Scorpaena maderensis and S. porcus to change body luminance. Figure shows median (points) and interquartile range (vertical bars) of the proportional change in body luminance every five seconds for 25 s, relative to initial (y = 0) and final luminance (y = 1) measured for each individual (see Methods). The black curve connects medians for each time point. The grey lines connect each data point per individual fish. The dotted horizontal lines indicate every 10% step from 0 to 100%, the dashed vertical line represents is a gap with no data between 25 and 60 s. N = 9 for S. maderensis and N = 13 for S. porcus
