Ultraviolet light is avoided in a manner indistinguishable from darkness and it competes with phototaxis. (A) Preference shown by the larvae for varying levels of UV stimuli vs. red, blue or both red and blue stimuli. (B) Preference of the larvae for darkness vs. red, blue or red and blue stimuli with increasing levels of the UV stimulus. (bars are mean ± SEM, N = 21 for the A panels, N = 20 for the B panels, both with fish from several clutches. Stars represent a p-value < 0.05 in a paired bootstrap test comparing the lowest power value to the others).
