世界之旅:環菊珊瑚,紅海

“一株環菊珊瑚在紫外線的照射下，隨着色彩而顫動好像被從裏面照亮着。這種珊瑚吸收不可見的紫外光，然後發出紛亂的橘色可見光。這叫做“熒光”——種近乎純魔術的物理學和生物學現象。”

——摘自1997年《國家地理雜誌》8月號《海底新發現》

Red Sea, Knob Coral
"Illuminated by ultraviolet light, a knob coral pulsates with color as if lit from within. The coral absorbs the invisible ultraviolet light, then emits wild orange visible light. This is called fluorescence, a phenomenon of physics and biology that borders on pure magic."

—From "A New Light in the Sea," August 1997, National Geographic magazine
