Some deep-sea organisms are known to use bioluminescence as a lure, to attract prey with a little glow imitating the movements of their favorite fish, or like fireflies, as a sexual attractant to find mates. While there are many possible evolutionary theories for the survival value of bioluminescence, one of the most fascinating is to _________________. The color of almost all bioluminescent molecules is blue-green, the same color as the ocean above. By self-glowing blue-green, the creatures no longer cast a shadow or create a silhouette, especially when viewed from below against the brighter waters above. Rather, by glowing themselves, they can blend into the sparkles, reflections, and scattered blue-green glow of sunlight or moonlight. Thus, they are most likely making their own light not to see, but to be un-seen.
