最近的研究表明，一些鱼类在社交信号中使用紫外线。使用反射分光光度法，我们发现，繁殖活跃的男性刺鱼也反映在紫外线（300-400 nm）。几个身体区域显示出在紫外波段的反射峰。银色的区域比红色或深色的区域反射更强。一个种群内的雄性在紫外线反射方面存在差异。一个特定区域的紫外线对比度与身体状况呈正相关。
Recent studies evidenced that some fishes use ultraviolet light in social signalling. Using reflection spectrophotometry we showed that reproductively active male sticklebacks also reflect in the UV-light (300-400 nm). Several body regions showed a reflectance peak in the UV-waveband. Silvery appearing regions reflected stronger than red-coloured or darker ones. Males within one population varied in UV-reflection. The UV-contrast of one particular region was positively correlated with physical condition.
