Difference in fluorescent area (absolute pixel count). R²_marg = 0.373, R²_cond = 0.804
Medium/orange–dark/grey	2244.95	1399.03	3278.23	1364.06	737.62	2350.44
Medium/orange–light/grey	− 2213.41	− 3711.56	− 897.32	− 924.62	− 2048.1	− 55.90

Estimated effect sizes are reported as the median difference and its 95% compatibility intervals (CIs), calculated from 10,000 simulations of the posterior distribution of model parameters. N = 21 for Scorpaena maderensis and N = 16 for S. porcus. Effect size strength increases with increasing deviation of median differences from zero, and the robustness of the result increases with decreasing degree of overlap of the 95% compatibility intervals (CIs) with zero
