[National Geographic] Knob Coral (혹산호)
Red Sea
1997
David Doubilet
“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
