揭示了五年后fishes from the Red Sea fluoresce red，在海洋和水族馆中的新研究表明，许多海洋鱼类荧光各异的各种颜色。当暴露于高能量蓝光时，有180种在广泛的礁鱼家族和属中显示出生物荧光的颜色。
Familiar fishes from gobies to blennies, frogfish to surgeonfish and even some elasmobranchs like sharks adn rays all have some pigments that are active in the fluorescent lighting spectrum. What is particularly exciting about this research is how certain cryptic fish like frogfish and scorpionfish may be almost impossible to see when they are sitting camouflaged in their natural habitat, but have patterns that highlight them like a marker when viewed under lighting that makes them fluoresce.
As most reefers know, the ocean water filters out the low energy red end of the spectrum leaving behind lots of narrow bandwidth light in the high energy blue spectrum – this is why our corals thrive on blue light and why so many colors we yearn for are excited under blues. Although it doesn’t surprise us that ocean life has evolved to use fluorescence for communication and visual cues, this research is the first time the ubiquity of bio-fluorescence has been demonstrated in marine fish.
So next time you’re picking out lights or lamps for your fish only aquarium, consider throwing some deep blue over them just to help their colors pop a bit more – fish kept under reef lighting always look so much better than some tired old tubes.[WIRED]
