利用原位光谱数据和视觉系统建模，我们研究了gfp样蛋白质赋予造礁珊瑚的颜色是否不仅对人类，而且对占据珊瑚礁不同生态位的鱼类来说都是五颜六色的。一些类似gfp的蛋白质，尤其是荧光绿色和非荧光色蛋白，确实能产生强烈的颜色信号。一个意想不到的发现是，荧光蛋白也可能使珊瑚在鱼类眼中显得不那么鲜艳，抵消了内共生藻类光合色素吸收的影响，这可能是一种保护植物免受食草动物侵害的形式。我们得出结论，gfp决定的珊瑚颜色可能是珊瑚鱼视觉生态的重要因素。
Using in situ spectrometry data and visual system modeling, we investigate whether the colors conferred to the reef-building corals by GFP-like proteins would look colorful not only to humans, but also to fish occupying different ecological niches on the reef. Some GFP-like proteins, most notably fluorescent greens and nonfluorescent chromoproteins, indeed generate intense color signals. An unexpected finding was that fluorescent proteins might also make corals appear less colorful to fish, counterbalancing the effect of absorption by the photosynthetic pigments of the endosymbiotic algae, which might be a form of protection against herbivores. We conclude that GFP-determined coloration of corals may be an important factor in visual ecology of the reef fishes.
