“一株環(huán)菊珊瑚在紫外線的照射下，隨著色彩而顫動(dòng)好像被從里面照亮著。這種珊瑚吸收不可見的紫外光，然后發(fā)出紛亂的橘色可見光。這叫做“熒光”——種近乎純魔術(shù)的物理學(xué)和生物學(xué)現(xiàn)象。”

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
