珊瑚礁中的珊瑚荧光现象虽然在浅水中得到了很好的描述，但在很大程度上仍未得到研究。我们发现，在以色列埃拉特的大学间海洋科学研究所(IUI)珊瑚礁中，许多硬壳动物物种的代表在50-60米深的地方发出明亮的荧光。其中一些荧光物种在中层深度(40-100米)有分布最大值。来自这些深度的几个个体显示出黄色或橙红色的荧光，后者基本上不存在于该珊瑚礁最浅部分的珊瑚中。我们通过实验证明，在某些情况下，荧光色素的产生与光照无关；而在另一些情况下，当动物被置于黑暗中时，荧光信号会改变或丢失。此外，我们还表明，在水下光场中没有紫外光波长的深处，也可以发生短波长光介导的荧光颜料从绿光到红光的光转化。在浅水珊瑚中常见的关于组织荧光颜色的种内颜色多态也在中游物种中观察到。我们的结果表明，中生礁中的荧光色素具有独特的生物学功能，并为珊瑚礁监测和生物医学成像提供了潜在的应用前景。
The phenomenon of coral fluorescence in mesophotic reefs, although well described for shallow waters, remains largely unstudied. We found that representatives of many scleractinian species are brightly fluorescent at depths of 50–60 m at the Interuniversity Institute for Marine Sciences (IUI) reef in Eilat, Israel. Some of these fluorescent species have distribution maxima at mesophotic depths (40–100 m). Several individuals from these depths displayed yellow or orange-red fluorescence, the latter being essentially absent in corals from the shallowest parts of this reef. We demonstrate experimentally that in some cases the production of fluorescent pigments is independent of the exposure to light; while in others, the fluorescence signature is altered or lost when the animals are kept in darkness. Furthermore, we show that green-to-red photoconversion of fluorescent pigments mediated by short-wavelength light can occur also at depths where ultraviolet wavelengths are absent from the underwater light field. Intraspecific colour polymorphisms regarding the colour of the tissue fluorescence, common among shallow water corals, were also observed for mesophotic species. Our results suggest that fluorescent pigments in mesophotic reefs fulfil a distinct biological function and offer promising application potential for coral-reef monitoring and biomedical imaging.
