← Nature & AnimalsWhich outcome occurs when a cuttlefish encounters monochromatic light?
A)Pupil constricts enhancing depth perception
B)Iridescent reflection ceases instantaneously
C)Chromatic camouflage fails over time✓
D)Ammonia excretion rate briefly increases
💡 Explanation
Chromatic camouflage fails because cuttlefish rely on iridophores exhibiting structural coloration for multi-spectral reflectance. Loss of spectral contrast impairs the 'photonic crystal' tuning mechanism; therefore, camouflage weakens, rather than enhancing perception under such restrictive perception conditions.
