And what about the poor octopus, no press for it. 
It’s interesting that instead of being bioluminescent they need light from an outside source in order to activate their fluorescence, like a glow-in-the-dark watch dial. When I was a kid in the '60s I had a handheld ultraviolet lamp for examining fluorescent mineral specimens, back when such equipment was fairly expensive. The coral and eel look as beautiful as any of those minerals.
